tantalum boride  

chemical formula: TaB2 

CAS:12007-07-7 

EINECS:234-496-7 

Molecular weight: 191.759 

Melting point: 3140 ℃ 

Density: 11.200 

Appearance: Black gray powder 

Property: Its appearance is usually black hexagonal crystal, insoluble in water, acid solutions, and alkali solutions, but soluble in molten alkali and sodium carbonate. The resistivity of tantalum diboride is 33-75 μ Ω· cm, and it has high thermal conductivity and heat generation. 

Synthesis method: 

1) High temperature synthesis method: Mix tantalum and boron powders in a certain proportion and react at high temperature to form tantalum diboride. This method usually requires higher temperatures and longer reaction times. 

2) Chemical vapor deposition method: Tantalum diboride is generated in the gas phase through chemical reactions and deposited on the substrate material. This method can prepare high-quality tantalum diboride thin films or coatings. 

3) Sol gel method: dissolve the compound containing tantalum and boron in the solvent to form a sol, and then prepare tantalum diboride through gel, drying, sintering and other steps. 

Product Usage: 

Due to its unique physical and chemical properties, tantalum diboride has a wide range of applications in multiple fields: 

Ultra high temperature ceramic materials: Due to its high melting point and wear resistance, tantalum diboride is an ideal choice for manufacturing ultra-high temperature ceramic materials. 

Hard material: As a reinforcement of hard materials, it can improve the wear resistance and service life of the material. 

Composite materials: Tantalum diboride can be combined with other materials to form composite materials with excellent properties, which are used in various high-tech fields. 

Conductive material: Tantalum diboride has excellent conductivity and can be applied in fields such as electronics and electrical engineering. 

Storage method: This product should be sealed and stored in a dry and cool environment. It should not be exposed to air for a long time to prevent moisture from causing aggregation, affecting dispersion performance and usage effect. In addition, it should be avoided from heavy pressure and not in contact with oxidants. It should be transported as ordinary goods.
