Silicon carbide mirrors deliver thermal deformation 1/50th that of glass, 200 W/mK thermal conductivity, and sub-nanometer surface roughness (Ra ≤ 0.5nm). With specific stiffness 4x fused silica and operating temps from -200°C to 1650°C, SiC is the material of choice for space telescopes, EUV lithography, and kW-class laser systems. RB-SiC for cost-effective large optics, CVD-SiC for ultra-precision. Jifeng Ceramics manufactures custom SiC mirrors up to 1.5m+ with full polish-coat-assembly integration. #sicmirror #siliconcarbide #spaceoptics #laseroptics #jifengceramics

Aluminum nitride (AlN) ceramics conduct heat 5–7 times better than alumina—up to 230 W/mK—while maintaining 15 kV/mm electrical insulation. With a thermal expansion coefficient matched to silicon, AlN substrates eliminate thermal stress in IGBT modules, 5G RF packages, and high-power LEDs. Non-toxic, RoHS compliant, and the smart replacement for beryllium oxide. Jifeng Ceramics supplies graded AlN substrates and custom components for the world's most demanding electronics. #aluminumnitride #aln #thermalmanagement #electronicpackaging #jifengceramics
