<P>PROBLEM TO BE SOLVED: To provide a thermally disappearing resin particle capable of being decomposed at a low temperature in a short time in a low-oxygen concentration atmosphere, leaving very little residue of a resin component, and hardly causing transformation and breakage of an obtained sintered inorganic material when used as a pore-forming agent or the like; and to provide a method for producing the thermally disappearing resin particle, a method for producing a sintered inorganic material, and the sintered inorganic material. <P>SOLUTION: The thermally disappearing resin particle contains a polyoxyalkylene resin. The resin particles of ≥90 wt.% disappear within 2 hr by being heated to a prescribed temperature of 100-350°C in the atmosphere of ≤5% oxygen concentration, and the residue of the resin components becomes ≤0.01 wt.% within 1 hr when the resin particles after disappearance of ≥90 wt.% are further heated to a prescribed temperature of 200-400°C. <P>COPYRIGHT: (C)2008,JPO&INPIT |
