Superfine TaB2 Powder Tantalum Boride Nano Powder

Overview of Tantalum Boride

Tantalum diboride appears as a gray powder that is not soluble in acid, nitric acid, or aqua regia. It shows slight solubility in hot sulfuric acid and hydrofluoric acid and is soluble in molten alkali and sodium carbonate. The Vickers hardness of both the TaB2 film and crystal is approximately 30 GPa. These materials exhibit stability against oxidation and acid corrosion up to temperatures of 700°C. TaB2 shares a hexagonal structure with other diborides, such as Alb2 and MGB2. It is characterized by specific space groups, including TAB (orthorhombic crystal system, iodized (I), Cmcm), TA5B6 (Cm), TA3B4 (IMmm), and TAB2 (hexagonal, aluminum diboride) type, P6/mm2.

Features of Tantalum Boride TaB2 Powder

TaB2 powder is a high-temperature inorganic compound with a metallic luster. It exhibits high hardness and wear resistance, making it ideal for use in ultra-high temperature ceramics, hard materials, and composites. This powder is stable under normal conditions but may react with other compounds under high temperatures or specific conditions. To preserve its quality, it is recommended to store it in a well-ventilated area away from direct sunlight and humidity, using a sealed container to shield it from the environment. Its excellent electrical properties also make it a viable option for use in various electronic and electrical devices.

Applications of Tantalum Boride TaB2 Powder

Tantalum boride is a substance made from tantalum, and boron is known for its exceptional hardness. Its remarkable hardness makes it suitable for various applications such as high-temperature materials, abrasive materials, wear-resistant coatings, semiconductor films, electronic materials, rare earth materials, alloy materials, and more.
Tantalum diboride is a crystal that shines like metal and has a very high melting point, along with being resistant to wear and hard. It finds broad applications in areas such as ultra-high temperature ceramics, tough materials, and reinforcing composite materials.
Tantalum diboride also has thermal and electrical conductivity and is used in the chemical industry, building materials, defense industry, agriculture and other departments.|

Production Method of Tantalum Boride TaB2 Powder

The powder is created through a reaction with boron, carbon, and an oxidizing agent under vacuum or gas protection. Using the floating zone method, single crystals of Tab2 can be grown, reaching dimensions of about 1 cm in diameter and 6 cm in length. Tantalum films can be formed by depositing from gas mixtures of Tacl5, Bcl3, H2, and Ar at temperatures ranging from 540 to 800 °C. A single-phase TAB2 can be deposited with a specific gas flow ratio and temperature conditions. In contrast, a single-phase TAB can be formed at different gas flow ratios and temperatures.

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.

FAQs of Tantalum Boride TaB2 Powder

Q1

What is TaB2 material?

Answer: Tantalum Diboride Powder, identified by its CAS number 12007-35-1, is a grey-colored powder with the chemical composition TaB2. It exhibits a high level of resistance to dissolution, being utterly unaffected by hydrochloric acid, nitric acid, and aqua regia while showing limited solubility in hot sulfuric acid and hydrofluoric acid. However, it readily dissolves in molten alkali and sodium carbonate solutions.

Q2

What is the hardness of tantalum boride?

Answer:TaB and TaB2 films and crystals exhibit a Vickers hardness of approximately 30 GPa. These materials are resistant to oxidation at temperatures lower than 700 °C and acid corrosion. TaB2 shares the hexagonal structure found in many diborides, such as AlB2 and MgB2.
