The Preparation and Application of Titanium Diboride Powder

Gray or gray-black titanium diboride powder has a hexagonal AlB2 crystal structure. High hardness and a melting point of 2980°C make titanium diboride a very strong metal. The titanium diboride’s anti-oxidation temperature in air can exceed 1000. Additionally, it is very stable in HCl as well as HF acid. It is used primarily to make composite ceramic products. It is resistant to corrosion, so titanium diboride may be used in making molten molten crucibles or electrolytic cell electrodes.

Titanium Diboride Preparation

The most common methods of preparing titanium dioxide raw materials include: carbothermic, self-propagating higher temperature and synthesis method; mechanochemical react method; vapor deposition, ball milling, etc.

1.Carbothermal reducing method Utilizing titanium oxides and boron dioxides as raw materials and carbon black as an reducing agent, carbon tube furnace long-term high temperature carbon reduction treatment, and carbon tube furnace carbon tube furnace carbon-tube furnace as the reducing agent, the purity level of the powder used to synthesize titanium diboride is affected by the powder’s purity. This is an industrial process. It has the disadvantage of having a very large particle size, and high impurity.

2.Self-propagating high temperature synthesis (SHS). The general idea is to first press the material to be reacted to a block and to then ignite one end to inflame the reaction. Due to the enormous heat generated by the reaction, the reactions of the other materials cause them to react and a flame-like phenomenon is produced. As the combustion wave moves forward, the mixture of raw materials is converted into final products. You can prepare a titanium diboride product directly by using the self-propagating high temperature synthesis technique in combination with other technical means.

3.Mechanochemical reaction technique (MR) Reactant powder is put in high-energy ballmills. This causes the powder to be repeatedly crushed by the grinding balls. Through the violent friction and collision with the ball milling medium, the mechanical energy can be transformed into chemical energy. The reactants are synthesized by the reaction of these reactions. The advantages of the mechanochemical reactions method are that it is much more cost-effective than the previous two methods of making titanium diboride.

Titanium Diboride

It is possible to combine titanium diboride with its composite materials and with other metals or ceramic-based polmers to create a variety of materials that have commercial value.

One use for titanium diboride is to refine grain and strengthen particles. You can mix it with aluminum-, copper-based titanium-aluminum alloys and iron to improve its mechanical and physical properties.

2.Titanium dioxide can be mixed with nonoxide ceramics like silicon carbide or aluminum nitride. Or, it can be combined with oxide ceramic materials, such as alumina.

PTC heating ceramics are made from 3.Titanium Diboride particles and high-performance epoxy resin. They have the following characteristics: safety, reliability, power conservation, ease of processing, molding, and simplicity. It is used to upgrade household appliances, such as hot air heating, by making electric irons, blankets, ovens, or electric conditioners.

4.Titanium dioxide has excellent electrical conductivity. It is also resistant to molten metallic corrosion. This can be used for making molten metal cathodes, sparkplugs, and evaporators.

5. The good wettability and durability of titanium diboride (and metal aluminum liquid) can help reduce the energy consumption and increase the lifespan of aluminum electrolytic cells.

6. You can use titanium diboride to create ceramic cutting tools. This can be used to make wire drawing tools, extrusion and sealing dies as well as finishing tools.
