Tantalum Boride Powder

tantalum diboride or tantalum boride is gray powder. The Tantalum diboride has a pH of and is insoluble in nitric, hydrofluoric or acidic solutions. Slightly soluble with hot hydrofluoric or sulfuric acid. Solvent in sodium carbonate and molten alkali. Crystal and TaB2 films have a Vickers Hardness around 30 GPa. These materials are resistant to acid corrosion and oxidation up to 700degC.

TaB2 shares the same hexagonal shape as most diborides. (Alb 2, MGB2,etc.). The following space groups also exist: TAB, (orthogonal crystal system, iodized, (I), Cmcm),TA5B6, (Cmmm),TA3B4 IMmm, TAB2, (hexagonal diboride type, P6/mm2)

What is the production process of Tantalum Boride Powder ?

Under vacuum or gas cylinder protection, either the carbon-oxidizing mixture and boron dioxide is made, or the powder is prepared through reaction with boron.

The floating zone method allows for the production of single crystals (about 1cm in diameter and about 6cm in length) of Tab2.

At temperatures over 600degC, TAB (single-phase), a mixture of Tacl-5-Bcl3 and H-2-Ar can be used to deposit a tantalum boride film.

Tab2 nanocrystals can be synthesized successfully by reducing NaBH4 to Ta2O5 with a molecular ratio of 1:1:4 under argon at 700-900degC.

Ta 2 O 5 + 6.5 NaBH 4 -2 TAB 2 + 4 Na (G, L) + 2.5 NaBO 2 + 13 H 2 (G)

Tantalum boride, which is composed of tantalum boron is a compound that is known for having an extremely high degree of hardness. Tantalum diboride, due to its high degree of hardness, can be used for high temperature materials and abrasives as well wear-resistant coatings.

Tantalum diboride, a metallic luster crystalline material with a high melting temperature and wear resistance, is hard. It is widely applied in ultra-high temperatures ceramic materials, hard material or composite materials reinforcement.

Tantalum Diboride has also a thermal and electrical conductivity. It is used by the chemical industry, metallurgy building materials, defence industry, agriculture, and many other departments.

Store Tantalum Boride TaB2 powder in the following conditions:

TaB powder will be affected by dampness and its effects on dispersion and use if it is not stored in a dry and cool room. TaB should also not be exposed to stress.

Packing & Shipping of Tantalum Boride (TaB2) Powder:
