Microporous Merane - an overview | ScienceDirect Topics

Microporous meranes can also be fabried from silicon carbide (SiC), which offers greater chemical and thermal stability than silicon dioxide (SiO 2). Silicon carbide (SiC) meranes are formed through the controlled pyrolysis of organic silanes, such as polycarbosilane and polydimethylsilane, in inert atmospheres up to 1000 °C.
