Physico-chemical property:

Zirconium diboride powder has very high melting point, strength, hardness and conductivity (and the conductivity temperature coefficient is positive), as well as low thermal expansion coefficient, in addition, it has good chemical stability, complementary neutron, flame retardant, heat resistance, corrosion resistance and light weight and other special properties, so it has wide uses.

Zirconium diboride powder used for refractory material:

Zirconium diboride is an excellent special refractory material, which can be used as high temperature thermocouple protection sleeve, crucible of metallurgical metal, casting mold, etc. When zirconium diboride is used as thermocouple protection sleeve, due to its poor air tightness and electrical conductivity, it must cooperate with aluminum oxide inner sleeve, in order to effectively measure temperature.The thermocouple sleeve of this material can be used for a long time in molten iron, brass and copper melt.

Zirconium diboride can also be used as an antioxidant of refractories, refractories added zirconium diboride, can form a liquid phase protective layer, thereby preventing the invasion of oxygen, played an antioxidant role, after adding, the performance of products, such as oxidation resistance, corrosion resistance and thermal shock resistance will be greatly improved.
