About Cadmium Sulfide CdS Powder :
Cadmium sulfide is an inorganic substance with a chemical formula of CdS. There are two crystals, the α-form is a lemon yellow powder, and the β-form is an orange-red powder. Slightly soluble in water, soluble in acid, slightly soluble in ammonia. Cadmium sulfide is a yellow solid. It has two different crystal structures in nature, namely, the rare minerals clinopyroxene and leucite, but it is more commonly used as an impurity substituent in zinc ore with similar structure, sphalerite and wurtzite, while zinc ore Sphalerite and wurtzite are the main economic sources of cadmium. As a compound that is easy to separate and purify, it is the main source of cadmium in all commercial applications. Its bright yellow color made it used as a pigment for the yellow paint “Cadmium Yellow” in the 18th century.
 
Like zinc sulfide, cadmium sulfide has two crystal forms. More stable hexagonal wurtzite structure (present in Greenockite mineral) and cubic zinc mixed structure (present in Hawleyite mineral). In both forms, cadmium and sulfur atoms have four coordinates. There is also a high-pressure form with a NaCl rock salt structure.
 
Cadmium sulfide is a direct bandgap semiconductor (energy gap 2.42 eV). The proximity of its bandgap to the wavelength of visible light gives it a colorful appearance.
Both polymorphs are piezoelectric, and the hexagon is also pyroelectric.
CdS crystal can be used as the gain medium of solid-state lasers.
CdS can be used in combination with other layers in the form of thin films for certain types of solar cells. CdS is also one of the first semiconductor materials used in thin-film transistors (TFT).

Industrial cadmium ore is leached into cadmium sulfate with sulfuric acid, adjusted to pH=3.5 and precipitated with sodium sulfide, and the pH should not be too low.
 
The production of pigments usually involves precipitation of CdS, washing of solid precipitates to remove soluble cadmium salts, then calcination (roasting) to convert them into hexagons, and then grinding to produce powders. When cadmium sulfide selenide is required, CdSe and CdS will co-precipitate, and cadmium selenide will be generated during the calcination step.
 
Applications of Cadmium Sulfide CdS Powder :
Cadmium sulfide is called cadmium yellow and is used to color enamel, glass, ceramics, plastics and paint.
Nickel yellow is suitable for coloring almost all resins and is translucent in plastics. There is a light-colored cadmium yellow containing zinc sulfide in polyethylene, and the molding processing time should be extended appropriately because zinc sulfide will promote the decomposition of polyethylene plastic and make it green. Cadmium yellow should not be mixed with pigments containing copper or copper salts to avoid the formation of black copper sulfide or green copper sulfate. Cadmium yellow and blue pigments can be mixed together to obtain green.
Cadmium sulfide is mainly used as a pigment owing to its good thermal stability, light and weather fastness, chemical resistance, and high opacity.
Other applications of cadmium sulfide are listed below:
Photoresistors
Thin-film transistors
Transducers
Solar cells
Electrochemical deposition

It starts to be oxidized when heated at 315°C in the air, and the temperature rises and the oxidation reaction accelerates. Molybdenum disulfide is insoluble in water, dilute acid and concentrated sulfuric acid. It is generally insoluble in other acids, alkalis and organic solvents, but it is soluble in aqua regia and boiling concentrated sulfuric acid. Slowly oxidized at 400 ℃ to generate molybdenum trioxide:
2MoS2+ 7 O2→ 2 MoO3 + 4 SO2 can be used to test the generated molybdenum trioxide with ferrotitanium reagent. First, the product is treated with sodium hydroxide or potassium hydroxide solution (the principle is to convert molybdenum trioxide into molybdate), and then the titanium iron reagent solution is added dropwise, which will react with the generated sodium molybdate or potassium molybdate to produce gold Yellow solution. This method is very sensitive, and trace amounts of molybdate can be detected. And if there is no molybdenum trioxide generated, the solution will not produce golden yellow, because molybdenum disulfide does not react with sodium hydroxide or potassium hydroxide solution.
Molybdenum disulfide can react with chlorine when heated to produce molybdenum pentachloride:
2 MoS2+ 7 Cl2→ 2 MoCl5+ 2 S2Cl2
Molybdenum disulfide and alkyl lithium react under control to form an intercalation compound (interlayer compound) LixMoS2. If it reacts with butyllithium, the product is LiMoS2.
Molybdenum disulfide has a high content of active sulfur, which is easy to cause corrosion to copper. It is discussed in many books and papers on lubricant additives. In addition, when the parts made of copper and its alloys need to be lubricated, it is not impossible to use molybdenum disulfide lubricating products, but also to add copper corrosion inhibitors. Feel free to send an inquiry to get the latest price if you would like to buy Molybdenum Disulfide MoS2 Powder in bulk.

Analysis of Molybdenum Disulfide MoS2 Powder:

How is Molybdenum Disulfide MoS2 Powder produced?
Natural law
MoS2 can be prepared by the natural method, namely the molybdenite concentrate purification method, which is to remove the acid-insoluble matter in the molybdenite concentrate, SiO2, Fe, Cu, by subjecting high-quality molybdenum concentrate to certain physical and chemical actions. Ca, Pb and other impurities are further refined to obtain nano-MoS2. However, the purity of the nano-MoS2 produced by the natural method is not high, and the purification technology needs to be further improved. When the temperature is lower than 400℃, it is recommended to use the most expensive MoS2 when working in ordinary atmosphere. It has lubricating ability below 1300℃, and it is recommended to use the cost-based MoS2.
Chemical synthesis
The synthetic method can produce sulfides with high purity, less impurities, and fine particle size, and can prepare sulfides that meet different functional requirements. Therefore, the production of nano sulfides by synthetic methods has always attracted much attention. There are many methods for preparing nano-MoS2, such as ammonium tetrathiomolybdate thermal decomposition method, hydrogen sulfide or sulfur vapor reduction method, high-energy ball milling method, carbon nanotube space confinement method, hydrothermal synthesis method, high-energy physical method and chemical method combination and many more.

Applications of Molybdenum Disulfide MoS2 Powder:
Molybdenum disulfide is diamagnetic, can convert linear photoconductors and semiconductors with P-type or N-type conductivity, and has the functions of rectification and energy conversion.
Molybdenum disulfide can also be synthesized as a catalyst for hydrocarbon dehydrogenation.
Molybdenum disulfide is also known as “the king of advanced solid lubricants”.
Molybdenum disulfide is a solid powder made from natural molybdenum concentrate chemically purified by changing the molecular structure.
Molybdenum disulfide has good dispersibility and does not need to be added. It can be added to various greases to form a colloidal state and will never replace it, thereby increasing the lubricity and extreme pressure of the grease.
Molybdenum disulfide is also suitable for high temperature, high pressure, high viscosity and high load mechanical working conditions to extend the service life of the equipment.
The main function of molybdenum disulfide as a friction material is to reduce friction at low temperatures, increase friction at high temperatures, and reduce combustion loss. Easily volatilize in the friction material.
Anti-friction: The size of disulfide particles formed by supersonic jet pulverization can reach 325-2500 mesh, the particle hardness is 1-1.5, and the friction coefficient is 0.05-0.1, so it can be used in friction materials to take advantage of the anti-friction effect;
Increased friction: Molybdenum disulfide is not conductive, and silicon carbide, molybdenum disulfide, molybdenum trisulfide and molybdenum trioxide are present. When the temperature of the friction material rises sharply due to friction, the shrinking molybdenum trioxide particles gradually heat up and expand, thereby increasing the friction in the axial direction.
Antioxidant: Molybdenum disulfide is obtained through a comprehensive chemical purification reaction, and its pH value changes 7-8, slightly alkaline. It covers the surface of the friction material, which can protect other materials from oxidation, especially making it difficult for other materials to move and enhancing adhesion.
