■ Specifications

Product overview:

Zirconium carbide is a kind of important high temperature structural material with high melting point, high strength and corrosion resistance. It has the characteristics of efficient absorption of visible light, reflection of infrared and energy storage.

Main purpose:

New thermal insulation and temperature regulation textile: zirconium carbide has the characteristics of efficient absorption of visible light and reflection of infrared. When it absorbs the short wavelength energy below 2 µ m accounting for 95% of sunlight, it can store the energy in the material through thermal conversion. It also has the characteristics of reflecting more than 2 µ m infrared wavelength. The infrared wavelength generated by the human body is about 10 µ M,and when people wear textile clothes containing ZrC, the infrared of the human body will not easily emit outward. Therefore, zirconium carbide has ideal characteristics of heat absorption and heat storage .

High temperature resistant coatings and structural materials: zirconium carbide ceramics have high melting point (3540 ℃) and good mechanical properties. Especially in the harsh environment such as high temperature, it has excellent high temperature resistance. It is one of the essential materials in the aerospace field.

Cemented carbide additive: zirconium carbide is an important structural material with high melting point, high strength and corrosion resistance. Its excellent characteristics make it have great application space in cemented carbide. The strength and corrosion resistance of cemented carbide can get great improvement when nano ZrC is added.

Metal coating material: low density loose zirconium carbide coating has good thermal stress resistance and insulation performance, and can be used as insulation material; The dense zirconium carbide coating with high density has good impermeability and can be used as protective coating.

Nuclear industry: nano ZrC has high temperature strength, high hardness, small thermal neutron absorption cross section and good radiation resistance. It can replace silicon carbide (SiC) as a new material for coating the barrier layer of nuclear fuel particles.

Performance characteristics: nano ZrC has the characteristics of high purity (no impurity phase detected by XRD), small particle size (20nm), large specific surface area and high surface activity.

Precautions:This product should be stored in a cool and dry room to avoid heavy pressure. During use, it shall not be exposed to the air to avoid moisture absorption and agglomeration, which will affect the dispersion performance and use effect. Unpacked products shall be sealed or stored in vacuum.
