Method of producing permeable, porous molded bodies of silicon carbide |
摘要 |
A porous green-state body of carbon, with or without silicon carbide, made with a cokable binder, is crumbled to produce relatively coarse grains in the range from 0.2 to 10 mm and a fraction of the particles so produced with a much more limited range of grain size is then used to produce a second green-state body, which is then coked, siliconized if the silicon is not already provided in the making of the precursor body that was broken up, and converted into a silicon carbide body. If the siliconizing is done by immersion in a bath of molten silicon, the excess silicon is removed by vaporization or by boiling in sodium hydroxide solution.
