What is Titanium Diboride TiB2 Powder?

Introduction to Titanium Diboride Pulver

Titanium Diboride Pulver



This is a grayish or gray-black powder with hexagonal crystal structures. The melting point is 2900, the hardness (HV), 34GPaI and density is 4.52. It features wear resistance, acid resistance, thermal conductivity, thermal and electrical conductivity, low thermal extension coefficient, excellent chemical stability and heat resistance.

Titanium Diboride powder’s Physical and Chemical Properties

Titanium diboride

Has a 1000-hour oxidation resistance in the air. It is stable in HCI/HF acids. But it reacts with H2SO4/HNO3. It is easily destroyed by alkali.

The hot pressing


The temperature at which the theoretical density is reached is 1800-1900 C (with the addition a small amount if metal or carbide sintering AIDS). You will need to use more sintering ingredients and heats that exceed 2000°C for press-free interfacing.


This is the most stable among several titanium-boron compound. It is a quasi-metallic hexagonal compound with a C32 structural structure and covalent bonds. The total crystal’s structural parameters are 0.3028nm (for A) and 0.3228nm (for C). This two-dimensional network structure is formed by the boron and titan atomic plans. B is covalently bond with three other Bs and an extra electron forms large p bonds. The layer structure in boron molecules is similar to graphite. While the outer electrons from Ti determine the electrical conductivity and metallic shine of TiB2, the Ti-B bonds between boron and titan atoms determine the high hardness, and brittleness. TiB2 is not susceptible to sintering. It is often densified through hot pressing or hot Isostatic pressing. TiB2 can be sintered press-free but liquid forming additions such as iron and chromium are needed to achieve high density.

Titanium Diboride Powder Applications

1. Titanium diboride can be used in rocket nozzle, electrical contact and high-temperature electrode materials. It can also serve as an abrasive.

2. It is used for tool ceramics, ceramics, conductive, wear resistant, and corrosion-resistant coating.

3. Useful for making conductive composites. Vacuum aluminum plating equipment is primarily used to make conductive boron, nitride.

4. It is used for cutting ceramic tools and their parts. Produce titanium diboride ceramics.

5. As a composite ceramic materials. Use titanium diboride as a component of many composite materials.

6. It can be used to make armor protection material.

7. Cathode material to aluminum electrolysis. Cathode material for aluminum electrolysis. The electrolytic aluminum cell’s power consumption is decreased due to the excellent wettability and the long life.

8. Al, Fe, Cu and other metal materials strengthening agents can be used to make PTC heating and flexible PTC material.

9. It can be used as a rocket nozzle, an electrical contact, or electrode material.
