Tantalum Boride Powder
Tantalum boride or tantalum diboride is a powdery gray color. The Tantalum diboride has a pH of and is insoluble in nitric, hydrofluoric or acidic solutions. The material is slightly soluble when heated in sulfuric or hydrofluoric acids. However, it is soluble with molten sodium carbonate and 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.). It also has space groups such as TAB (orthogonal crystal system, iodized, (I), Cmcm), and TA5B6.

Under vacuum or gas cylinder protection, either the carbon-oxidizing mixture and boron dioxide is prepared, or the powder is prepared through reaction with the element 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 Ta 2O5 with a molecular ratio of 1:14 M:B 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)

Application Tantalum Boride TaB2 powder
Tantalum boride, which is composed of tantalum boron is characterized by its extreme 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:
