A strong but lightweight mirror for space, made from silicon carbide ceramic, is being subjected to the temperature levels and vacuum encountered in orbit. The 95 cm-diameter mirror consists of three separate petals fused together ahead of grinding and polishing.
A SiC fiber was synthesized from polycarbosilane-polyvinylsilane (PCS-PVS) blend polymer with electron beam curing under vacuum. The SiC fiber obtained from the blend polymer which contains 20 wt% of PVS in PCS was very fine and flexible, and its average diameter was 7 μm. Although the yield of the SiC fiber from the blend polymer was 73%, that is lower than that of 82% from PCS, with the

E-beam Evaporation of Silicon (Si (P-type)) Silicon is rated as fair for e-beam evaporation. We refer to a material''s evaporation temperature as the temperature required to achieve a vapor pressure of 10-2 Torr. At this vapor pressure, a high deposition rate is possible in a system that has a normal source-to-substrate geometry.
