Preparation and application of tantalum diboride

Preparation method of tantalum boride powder

Tantalum boride powder is mainly prepared by thermally reducing tantalum pentoxide powder and carbon black or graphite powder. The reaction equation is 2Ta205 + B4C + 15C + 2B203 = 4TaB2 + 16C0. The above reaction process belongs to the solid-solid reaction type, and the reaction process is controlled by material diffusion. The disadvantage of this method is that the mixing of tantalum pentoxide powder and carbon black or graphite powder is not uniform, and the activity of carbon black or graphite powder is low, which makes the tantalum pentoxide powder incompletely reduced to become impurities in the product. In addition, the carbon black or graphite powder remaining in the tantalum boride powder has low activity and requires high temperature (>600°C) in the decarburization process to generate carbon monoxide or carbon dioxide in an oxidizing atmosphere to eliminate C.

Overview of tantalum TaB2 powder

The boride TaB2 has the same hexagonal structure as most diborides (Alb 2, MGB2, etc.), and also has the following space group: TAB (orthogonal crystal system, iodide ((I), Cmcm), TA5B6 (Cmmm), TA3B4 (IMmm), TAB2 (hexagonal, aluminum diboride) type, P6 / mm2).

Application of tantalum boride TaB2 powder

Tantalum boride is a compound of tantalum and boron and therefore attracts attention due to its extremely high hardness. Due to its high hardness, tantalum diboride can be used as high-temperature materials and abrasives, as well as wear-resistant coatings, semiconductor films, electronic materials, ceramic materials, rare earth materials, alloy materials, etc.

Tantalum diboride is a metallic luster crystal with high melting point, wear resistance and hardness. It is widely used in the field of reinforcement of ultra-high temperature ceramic materials, hard materials or composite materials.

Tantalum diboride also has thermal and electrical conductivity, and can be used in the chemical industry, metallurgy, building materials, defense industry, agriculture and other sectors.
