The Preparation and Application of Titanium Diboride Powder

Titanium diboride powder The hexagonal (AlB2) structure of the crystals is grayish-black. It is very hard and has a melting temperature of 2980degC. It is stable to HCl, HF and anti-oxidation temperatures. Titanium Diboride is used primarily for the preparation of composite ceramic products. Due to its ability to resist corrosion, titanium diboride may be used for the production of electrolytic cell electrodes and molten metallic crucibles.

Preparation and Use of Titanium Diboride

There are many methods that can be used to prepare titanium diboride. These include the carbothermic method of reduction, the self-propagating method at high temperature, the mechanochemical method of reaction, and ball milling.
1.Carbothermal Reduction Method
The quality of the titanium diboride powder synthesized depends on the powder purity. This is achieved by using titanium and boron oxids as raw materials. Carbon black is used as a reducing agent. This process is widely used in industrial production. The powder obtained from this process has large particles and is high in impurities.

Self-propagating High-Temperature Synthesis (SHS)
In general, this method is to compress the raw material mixture that will be reacted and ignite one end of the resulting block. The reaction releases a huge amount of heat, which causes adjacent materials to react. Eventually a combustion waves spreading at speed v forms. As the combustion waves advance, the raw materials are transformed into the finished product. The self-propagating, high-temperature method can be combined with special technical means to produce a dense material of titanium diboride.

3. Mechanical reaction method (MR).
The powder reactant is placed into a high-energy mill and is repeatedly deformed under the squeeze and shear of the grinding ball. The ball milling medium generates chemical energy through the violent friction. Comparing the two first methods of preparing titanium dioxide, the mechanochemical reactions method has advantages such as low synthesis temperatures, a wide range of raw material sources, and low costs.

The Application of Titanium Diboride

Titanium diboride can be mixed with ceramic polymers and other metals to create new materials that have commercial applications.

1.Titanium boride can serve as an additive for grain refinement or particle strengthening. It can be used to enhance the mechanical and physic properties of materials based on aluminum, copper and titanium-aluminum alloy.

It is possible to combine titanium diboride and non-oxide ceramics, such as silicon carbide, aluminum nitride or titanium carbide. Or, it can be combined with oxide ceramics, such as alumina.

PTC head-type materials and PTC heating ceramics can be created by mixing titanium diboride powder with high performance resin. They have many advantages, such as safety, energy saving, reliability and ease of processing and molding. These include electric irons (and blankets), electric ovens (and air conditioners), and electric blankets. This is a key high-tech to upgrade household appliances like hot-air heaters.

It has excellent resistance to corrosion caused by molten metallic sludge. It is used for evaporators as well as aluminum electrolytic cells cathodes, electrodes, contact heads, and molten-metal crucibles.

5. It is possible to reduce the energy consumption and extend the life of an aluminum electrolytic battery by coating the cathode with titanium diboride.

6. Titanium diboride may be used in the manufacture of ceramic tools and molds. It is used for the manufacture of finishing tools, extrusion and wire drawing dies.

The Characteristics of Titanium Diboride Ceramics And Preparation Method of Titanium Diboride

Metal borides, among many other compounds, have better performance at high temperatures than do metal carbides. As an example, titanium diboride (TiB2) The cermet product is more suitable for use in high temperature, high corrosive conditions.
The properties of titanium diboride both as structural materials and as functional materials

1. Structure materials. Due to its high strength, titanium boride can be used for tools, wire drawing films, sandblasting materials, and other hard tooling materials. It can also be added to composite materials.

2. Functional materials. It is therefore very useful to use titanium boride in functional materials. Titanium boride’s electrical properties can be used to create flexible PTC material.

There are many methods to prepare titanium diboride. These include the carbothermal method of reduction, the self-propagating method at high temperatures and synthesis, the mechanochemical method, and ball milling.

Reduce carbothermic toxicity using a reduction method
In a carbon tube oven, using titanium and boron oxids as raw materials with carbon black as the reducing agent for a long time, the purity of the titanium diboride is determined by the purity in the powder of the raw materials. This process is widely used in industrial production. The powder obtained from this process has large particles and high impurity levels.

Self-propagating heat synthesis (SHS).
In general, this method involves pressing the raw material mixture into a solid block. One end of the solid block is then ignited to ignite a reaction. The reaction releases a huge amount of heat, which causes adjacent materials to react. Eventually, a combustion-wave spreading at speed v forms. As the combustion wave moves forward, the raw materials are transformed into the finished product. Because of the self purifying effect of the self propagating high-temperature synthesizing process, the obtained powder can be easily sintered and external energy consumption is minimal. With the use of other technical means and special techniques, it is possible to prepare dense titanium diboride directly.

Titanium Diboride Powder Properties And Applications

It is important to note that the word “you” means “you”. titanium diboride The powder is grayish-black with a hexagonal structure (AlB2). It has a very hardness and a melting temperature of 2980degC. The titanium diboride anti-oxidation in the air can rise to 1000 degrees Celsius, and is stable with HCl acid and HF.

Titanium Diboride Powder Properties

Titanium diboride is the most stable of all boron-titanium compounds. It has C32 structure, and is combined as valence bonds. It is a hexagonal metalloid. The crystal’s structural parameters are: C is 0.3228nm; a is 0.302nm.
In the crystal, the boron plane and the titanium plane alternately form two-dimensional networks, where B is covalently linked with the other three borons, and a single electron forms a strong p bond. This graphite like layered structure between boron electrons and Ti outer layers determines TiB2’s good conductivity, metallic luster, and hardness.
