Can alumina be used at cryo temperature
WebThe tank is well guarded by bollards and the walls of a containment dike, and in a low-traffic area. I'm well aware that CS is not a cryogenic material, and it loses most of it's "toughness" by time it gets to ~0°F. Ideally a tank in this service should be austenitic stainless steel, a "cryo" grade material. WebSep 1, 1985 · Abstract. Thermal conductivity is measured on AI 2 O 3 ceramic, structural SiC and high thermal conductivity SiC (2 wt% BeO addition) ceramics at a temperature range of 4–300 K. These ceramics possess conductivity maxima, the values of which are 0.9 W cm −1 K −1 at ≈ 80 K for AI 2 O 3; 4 W cm −1 K −1 at ≈ 100 K for high thermal ...
