Reputation depends on quality, quality comes from Hard!
Zirocnia Ceramics:
HRA is 99, HV reaches 23.3 GPa. The high pressure promotes the sintering process of Si3N4 ceramics, reduces the sintering temperature and shortens the sintering process cycle. The Y2O-Al2O3 system composite sintering aid is effective for the sintering of Si3N4 ceramics And the mechanical properties increase with the increase of sintering temperature and pressure. Α-Si3N4 is an unstable phase under the conditions of 5.4 ～ 5.7 GPa, 1570 ～ 1770 K and Y2O–Al2O3 system as a sintering aid. Β-Si3N4 is the stable phase under this high temperature and high pressure condition. SiC is a highly covalently bonded compound, and its basic constituent unit is a coordinated tetrahedron (SiC4 or CSi4). According to the stacking order, there are more than 200 variants of SiC that have face-centered cubic structure The SiC is called β-SiC (3C-SiC), and β-SiC has high stability at less than 2100 ° C and is the main crystal phase of SiC. Other variants are called α-SiC [1] In terms of performance, SiC is widely used in aerospace, high aerospace, high hardness, high wear resistance, good thermal shock resistance, high thermal conductivity, strong oxidation resistance and chemical corrosion resistance. In the fields of chemical engineering and electronics, there is huge potential for development in high-temperature structural components and new electronic components.
