Titanium diboride: a new industrial ceramic raw material

What is titanium diboride?

Among many compounds, metal borides have better high-temperature performance than metal carbides. For example, diboride (TiB2) cermets are better suited to high temperature and high erosion conditions than titanium carbide (TiC) and tungsten carbide (WC) cermets.  Titanium diboride powder is gray (or gray-black) and ranks sixth among the ten materials with the highest melting point known in the world.  Oxidation resistance temperature in the air up to 1100℃, as a new type of ceramic material, has very excellent physical and chemical properties, in addition to the melting point is very high hardness, chemical stability, electrical and thermal conductivity, mechanical and mechanical properties at high temperature are extremely excellent.  

The characteristics of titanium diboride as structural materials and functional materials are as follows:

(1) Structural materials.  Titanium boride's high strength and hardness enable it to be used as a tool material, drawing film, sandblasting nozzle and hard tool material, and it can also be used as an additive in composite materials.

(2) Functional materials.  The resistivity of titanium boride is very similar to that of pure iron, so its application in functional materials is very promising.  Through the electrical properties of Titanium boride, flexible PTC materials can be made.  

Application direction of titanium diboride

Titanium diboride and its composite materials can be combined with other metal and ceramic polymer to form a series of new materials with commercial application value.  

(1) Titanium diboride can be used as grain refining and particle strengthening additive, and can be mixed into aluminum base, copper base titanium aluminum alloy and iron base materials, which can greatly improve the mechanical and physical and chemical properties of materials.  The effect of grain refinement and grain strengthening will be improved with the increase of purity and fineness of titanium diboride powder.

(2) Titanium diboride silicon carbide, aluminum nitride, boron nitride, titanium carbide, such as the oxide ceramic composite, can also with the alumina oxide ceramic materials such as composite, after a lot of experimental research show that the preparation of a new composite material has more excellent mechanical strength and resistance to fracture toughness, can be one of the high quality material of making armor materials.  

(3) Titanium diboride particles mixed with high performance resin can be made into PTC heating ceramics and head TYPE PTC materials, which has the characteristics of safety, power saving, reliability and easy processing and forming. It is a key new and high technology for the renewal of electric irons, electric blankets, electric ovens, air conditioners, hot air heaters and other household appliances.

(4) Titanium diboride excellent electrical conductivity and excellent corrosion resistance of molten metal, can be used to make evaporation vessels, molten metal crucible, aluminum electrolytic cell cathode, spark plug and other electrode and contact starting materials.  

(5) Because of the good wettability of titanium diboride and liquid aluminum, using titanium diboride as cathode coating material can reduce the power consumption of aluminum electrolytic cell and prolong the service life of aluminum electrolytic cell.  Titanium diboride can be used to make ceramic cutting tools and molds.  Can manufacture finishing tools, drawing die, extrusion die, sandblasting nozzle, sealing elements, etc.
