What is Zirconium Diboride ZrB2?

Zirconium boride includes zirconium monobboride, zirconium diboride, and zirconium lauraboride. Only zirconium diboride is stable over a wide temperature range. 

Zirconium diboride with the molecular formula ZrB2 is hexagonal, gray crystal or powder. 

Physicochemical Properties of Zirconium Diboride ZrB2

Its relative density is 5.8 and the melting point is 3040℃. High-temperature resistant, it has high strength at both room temperature and high temperature. Good thermal shock resistance, low resistance, oxidation resistance at high temperature. Metallic luster. 

Zirconium diboride has a very high melting point, strength, hardness, and conductivity (with positive conductivity and temperature coefficient), as well as a low coefficient of thermal expansion, good electrical conductivity, and chemical stability.

What is Zirconium Diboride ZrB2 Used For?

Zirconium boride powder has the properties of low density, high melting point, high hardness, high specific strength, high specific stiffness, good thermal conductivity, excellent electrical conductivity, excellent ablative resistance, and oxidation resistance.  Zirconium boride powder has been widely used in the fields of aerospace, military manufacturing, metallurgy, mining, and mechanical processing.

It is generally used as composite materials for cutting tool electrical and electronic material components. It can also be used as aerospace high-temperature-resistant materials, wear-resistant smooth solid materials, cutting tools, thermocouple protection tubes, and electrode materials for electrolysis of molten compounds. Especially suitable for use as the surface of rolling bearings. 

Zirconium Diboride ZrB2 Ceramics

Zirconium boride ceramics is a kind of ceramics with zirconium and boron compounds as the main components.

Zirconium diboride powder was synthesized from zirconium dioxide, tetraboron carbide, carbon black, and boron oxide in a carbon tube furnace at the temperature of 2000-2100℃. The ceramic products are then formed by conventional ceramic processing methods (or static forming) in a hydrogen atmosphere at 2050℃.

Zirconium boride ceramics have good high-temperature resistance, electrical and thermal conductivity, high hardness, and chemical stability.

They are mainly used for high-temperature thermocouple protection sleeves, heating elements, rocket nozzle, high-temperature heating elements, metal thermocouple electrodes, smelting aluminum, calcium, magnesium, lead, tin, and other metals and silicon crucible, mold, etc.
