About Tantalum Boride TaB2 Powder :
Tantalum diboride is a gray powder. Tantalum diboride is completely insoluble in acid, nitric acid and aqua regia. Slightly soluble in hot sulfuric acid and hydrofluoric acid, soluble in molten alkali and sodium carbonate. The Vickers hardness of the TaB2 film and crystal is about 30 GPa.These materials are stable to oxidation and acid corrosion up to 700°C.
TaB2 has the same hexagonal structure as most diborides (Alb 2, MGB2, etc.).It also has the following space groups: TAB (orthogonal-crystal system, iodized ((I), Cmcm), TA5B6 (Cmmm), TA3B4 (IMmm), TAB2 (hexagonal, aluminum diboride) type, P6 / mm2).

How is Tantalum Boride TaB2 Powder produced?
Under vacuum or cylinder gas protection, the powder is prepared by reacting with the element boron, or the mixture of carbon and oxidizing load and boron oxide is made.
Single crystals of Tab2 (about 1 cm in diameter and 6 cm in length) can be produced by the floating zone method.
Tantalum boride films can be deposited from gas mixtures of Tacl 5-Bcl3-H 2-Ar at temperatures of 540 — 800 °C.TAB 2 (single phase) is deposited at a feedstock gas flow ratio of six (BCL 3 / TACL 5) and at temperatures above 600°C.TAB (single-phase) was deposited at BCl 3 / TaCl 5 = 2-4 and T = 600-700°C.
Tab2 nanocrystals were successfully synthesized by reducing NaBH 4 to Ta 2O 5 with a molar ratio of 1:4 M: B at 700-900°C under argon.

Application of Tantalum Boride TaB2 Powder :
Tantalum boride is a compound of tantalum and boron and is noted for 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 a high melting point, wear-resistance and hardness. It is widely used in the fields of ultra-high temperature ceramic materials, hard materials or composite material reinforcement.
Tantalum diboride also has thermal and electrical conductivity and is used in the chemical industry, metallurgy, building materials, defense industry, agriculture and other departments.
Storage Condition of Tantalum Boride TaB2 Powder:
The damp reunion will affect TaB powder dispersion performance and using effects, therefore, tantalum boride TaB powder should be sealed in vacuum packing and stored in cool and dry room, the tantalum boride TaB powder can not be exposure to air. In addition, the TaB powder should be avoided under stress.
Packing & Shipping of Tantalum Boride TaB2 Powder:
