Preparation method of tantalum boride powder
Tantalum boride powderis mainly prepared by thermal reduction of tantalum pentoxide powder and carbon black or graphite powder. The reaction equation is 2Ta2O5+B4C+15C+2B2O3 = 4TaB2+16C0. The above reaction process is a solid-solid reaction type, and the reaction process is controlled by substance diffusion. The disadvantage of this method is that the tantalum pentoxide powder is not uniformly mixed with carbon black or graphite powder, and the activity of the carbon black or graphite powder is low, so that the tantalum pentoxide powder is incompletely reduced and becomes an impurity in the product. In addition, the carbon black or graphite powder remaining in the tantalum boride powder has low activity, and high temperature (>600°C) is required for decarburization, and carbon monoxide or carbon dioxide is generated 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 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, which has attracted 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 reinforcement field of ultra-high temperature ceramic materials, hard materials or composite materials.
Tantalum diboride also has thermal and electrical conductivity, and can be used in chemical, metallurgical, building materials, national defense, agriculture and other sectors.
