THERMALLY DISAPPEARING RESIN PARTICLE

摘要

It is intended to provide a thermally disappearing resin particle which can be decomposed at a low temperature and in a short time and gives a sintered body in which deformation or crack does not occur when being used as a binder or a weight-reducing material for a ceramic; a thermally disappearing hollow resin particle; a process for producing the thermally disappearing hollow resin particle; a ceramic composition which can be degreased and sintered at a low temperature in a short time and can give a molded body with high porosity without occurrence of deformation or crack even when a pore forming material is used in a large amount; and a process for producing a porous ceramic filter. The invention is directed to the thermally disappearing resin particles each of which contains a polyoxyalkylene resin and in which a portion corresponding to 10 % by weight or more of the whole particles disappears within 1 hour when the particles are heated to a predetermined temperature in the range from 100 to 300°C.
