Cobalt silicide CoSi2 physical properties

Properties: gray powder, cubic crystal.

Density (g/mL, 25/4℃): 5.3

Melting point (oC): 1277

Solubility: insoluble in water

Cobalt silicide CoSi2 synthesis method

According to the chemical composition ratio of CoSi2, the cobalt powder and silicon powder are mixed uniformly, and they are melted under the condition of isolating air, and kept at a temperature of 1150℃ for 100h to make them fully homogenized. The product is close to single-phase CoSi2.

Cobalt silicide CoSi2 ecological data

Usually it is not harmful to water. If there is no government permission, do not discharge the material into the surrounding environment.

Overview of cobalt silicide CoSi2 powder

Cobalt disilicide, chemical formula CoSi2. The molecular weight is 115.11. Dark brown rhomboid crystals. The melting point is 1277°C, the relative density is 5.3. It is oxidized at 1200°C and corrodes the surface. It reacts with fluorine at low temperatures and with chlorine at 300°C. Hydrogen fluoride, dilute solutions, concentrated nitric acid and sulfuric acid may also be severely attacked by molten alkali. It reacts slowly with boiling concentrated hydrochloric acid.

CoSi2 has low resistivity and good thermal stability, and is widely used as contacts in large-scale integrated circuits. Moreover, CoSi2 has a crystal structure similar to Si, so an epitaxial CoSi2/Si structure can be formed on a Si substrate to study the interface characteristics of epitaxial metal silicon.

Cobalt silicide CoSi2 powder application

Cobalt silicide CoSi2 powder is used in optoelectronic equipment, electronic equipment, energy equipment, lasers, semiconductors, etc.

Silicide nanostructures have potentially important applications in a series of nanoelectronics: Semiconductor silicide nanostructures (FeSi2) can be used to prepare nanoelectronic active devices, and may have very important applications in silicon-based nanolight emitting devices. Metal silicides (CoSi2, NiSi2) can be used as nanowires in future quantum computers and fault-tolerant terahertz nanocircuit computers. Since the epitaxial silicide conductor can be prepared on a silicon substrate, compared with ordinary metal nanowires, since there is no grain boundary, its performance will be greatly improved. Gold nanostructures can also be used as single- or multi-molecular nanoelectrodes for molecular electronics. During the processing of semiconductor components,
