Conversion to micro-pore ceramic of the colloid and the synthesis of pre-ceramic polymer stabilized metal colloid

摘要

(57) surface area is greater than ² / g 70m, also micropores smaller than 20 angstroms average width, [summary] The present invention has about 0.03cm ³ volume greater than ceramic 1g per the micro-pore structure I will provide a microporous ceramic material having a microporous open-celled structure. The present invention provides a preceramic composite intermediate composition comprising a mixture of metal particles of nanoscale size ceramic precursor. This pre-ceramic composite intermediate composition generates a micro-pore ceramic of the present invention and the thermal decomposition of ammonia in the atmosphere or under an inert atmosphere at a temperature of about 1100 ℃ less than the best. Furthermore, it provides a method for producing a microporous ceramics of the present invention consisting in pyrolyzing the composite intermediate is heated while controlling the temperature to a temperature of about 1100 ℃ below up to create a microporous ceramic product to.
