Zirocnia Ceramics:
Ceramic material refers to a kind of inorganic non-metallic material made by natural or synthetic compound after forming and high temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance, oxidation resistance, etc. It can be used as structural material and tool material due to Ceramics also have some special properties and can be used as functional materials. With domestic nano-Silicon Nitride powder as raw material, after gel injection molding, under the condition of flowing high-purity N2 as the controlled atmosphere, the relative density is 0.72, the structure is uniform, and the flexural strength is sintered at 1 510 °C. The effect of the purity of the raw materials, the sintering temperature and the immersion atmosphere on the dielectric properties of the ceramics was investigated for the Si3N4 radome material with a good dielectric properties of 89 MPa. Zirconium oxide has high hardness, Hv=18GPa~21?Gpa, HRA=91~93, second only to diamond, cubic BN, B4C and other superhard materials, low friction coefficient (O.1), self-lubricating Similar to the metal surface of the refueling (0.1--0.2)
It is a high temperature insoluble compound, has no melting point, and has high resistance to high temperature creep. The binder-free reaction sintered silicon nitride has a softening point of 1800 ° C or higher.
