What is Borides Powder?
Boride Poudre
The boron is combined with metals or non-metals. It is usually a mesenchymal material and does follow the valence laws. Except for zinc (Zn), cadmium (Cd), mercury (Hg), gallium (Ga), indium (In), thallium (Tl), germanium (Ge), tin (Sn), lead (Pb), bismuth (Bi).
Borides powder can be formed from other metals. These crystals are hard and have melting points. They are chemically inert and can not be dissolved with hot concentrated nitric. They can be combined directly with elements, or by reducing oxides and active metals. They can be used as superconducting and refractory materials.
Boron, a light metal, forms Borides Powder stable with transitional metals. The compounds with the highest melting points are formed from elements in groups IVA and VA or VIA. The structural characteristics of the boric atom determine the crystallographic structure of boride. Borides Powder’s chemical stability gradually decreases as it moves from IVA towards VIA. Borides Powder with the highest chemical stability include TiB2, ZrB2, & HfB2.
Boride Powder crystal structure
Between boron atoms, single bonds, dual bonds, networks and spatial frames are formed in the boride structure. As the proportion of boron increases in the boride, the structure unit becomes more complex.
In general, the more complex boron’s atomic structure is, the less likely that it will be hydrolyzed. Its resistance to oxidation or nitridation also increases.
In transition metal Borides Powder the chemical bond is between the metal and the boron. This electronic bond transforms the boron into a positively-charged ion.
Borides Powder: Preparation methods
Borides Powders are made primarily by melting refractory metals.
1.A direct reaction between metal and boron at high temperature results in the following formula:
Me+B—-MeB
Reducing metal oxide and boric acid with carbon is
2MeO+B2O3+5C—2MeB+5CO
Aluminum (silicon, Magnesium) Thermal method. Aluminium or silicon, magnesium reduces the oxides to generate metals and boron.
)—MeB+Al (Si,Mg) Oxide
Reducing metal oxides by boron carburide and carbon
4MeO+B4C+3C—4MeB+4CO
Reduce refractory metal oxides by using boron
xMeO+2xB—xMeB+(BO)x
Borides Powder: Use and nature
Boride has high conductivity as well as high melting points, hardness and stability. Boride’s thermal stability is also good because it has high thermal conductivity. The oxidation resistance at high temperatures of boride metals is based upon group IVB. Boride has the highest oxidation resistance.
Borides Powder do not react with humid air and dilute hydrochloric acids, but they do dissolve in nitric. Borides Powders are a mixture of metals and plastics. They have high conductivity as well as a positive coefficient of temperature resistance. Borides Powders Ti, Zr, Hf, and Zr have a better conductivity than the metals.
Boride’s creep resistance is excellent, which makes it a great material for gas turbines or rockets. Boride can also resist corrosion and heat shock, while maintaining strength. Borides Powder, carbides and Nitrides are the basis for a number of alloys or cermets that can be used in rocket structural components.
