cadmium nitride formula (Cd2(NO3)4), a white rhomboid crystal, possesses a relative density of 2.455 g/cm3. It is soluble in water and is a major constituent of the cadmium batteries used in portable electric vehicles. It is also a pigment and an intermediate in the production of other cadmium compounds.
The chemistry of CdN is highly complex, as it exhibits a variety of structures and properties. Among these, B18 is the most stable structure. It has a low bulk modulus and an excellent conductivity. Its thermodynamically favourable properties have led to its wide range of applications, including photoelectric cells and coatings in glass and porcelain.
Its high thermal stability and adsorption capacities make it a useful substance in the field of corrosion protection. It can be dissolved in water and is able to form solutions with various pH values. It is incompatible with reducing agents, organic materials and phosphorus.
A cadmium loaded metal-organic framework was prepared and characterized by a series of combustion analysis techniques, including carbon/hydrogen/nitrogen analysis, inductively coupled plasma spectroscopy, elemental and thermogravimetry-mass spectrometry. It showed a 2.5:1 cadmium to calcium ratio and a 15.5% content of volatile solvents.
It has a relatively high adsorption capacity for nickel, indicating its potential as a corrosion inhibitor and surface barrier. The adsorption capacity increases with increasing concentrations of the cadmium and decreases as the nickel is removed. Adsorption of cadmium to the support material is accompanied by an increase in its thermal stability, with a temperature rise of 0.1°C for each mol of the cadmium load.
