Zirconium carbide powder is a kind of a gray metallic powder with properities of corrosion resistance, high surface activation, high hardness, good thermal conductivity (20.5 W/m•K ) and electrical conductivity : resistivity ~43 μΩ•cm, high melting point : ~3530 °C...etc. Compared to other metal carbide powders, like WC tungsten carbide powder, tantalum carbide powder TaC powder, Hafnium carbide powder HfC powder, the density (6.73 g/cm3 ) is lower. Due to this properity, zirconium carbide powder ZrC powder is more suitable to be used in the field of re-entry vehicles, rocket in which low density and high temperature load-bearing capabilites and crucial requirements.
Advantage: Why Langfeng Metallic's carbide powder is better?
1. Use high purity raw material : zirconium oxide ZrO2, carbon black powder. Strictly control in raw material ensure the high purity of end product: zirconium carbide power.
2. Good grain-size distribution, contact us for SEM photo and PSD (particle size distribution) report;
3. Unique technology in additive process;
4. Unique sintering process ensure low oxygen and free carbon content, which bring high quality product;
Application
1. Nano size zirconium carbide powder: due to its characteristic of absorption visible light, reflection infrared and energy store, it is widely used on special textile fiber with the function of theraml isolation and heat storage, such as like bluejean, thermal underwear, winter gym suit....etc;
2. Zirconium carbide powder could be applied into new carbon complex function materail, improve performance on the garde of high temperature resistance and corrosion resistance. Now it is widely used in the field of military and aerospace.
3. Zirconium carbide powder also could be applied on the product of electrode, the fireproof crucible and negative pole electron emission material.
4. With the properity of high hardness, zirconium carbide powder also acts as an important abrasive .
5. zirconium carbide powder in size 40-60mesh (250-380um), 60-80mesh (180-250um), 80-100mesh (150-180um), 100-150 mesh(106-150um), 150-200mesh (75-106um), 200-400mesh (38-75um), 200-325mesh (45-75um), -325mesh (-45um ), -400mesh (-38um) is usually be used in the field of high heat resitance thermal sparay coating;
6. Zirconium carbide powder in APS (average particle size) FSSS 3-5 micron and FSSS 0.8-1.5 micron, usually be used as additive in cemented carbide products, like cutting tools...etc.
