| titleOfInvention | Manufacturing method of porous silicon oxynitride sintered body |
| abstract | The present invention relates to a method for producing a porous silicon oxynitride sintered body applied to a refractory tile of a space shuttle; Its purpose is to provide a method for producing a porous silicon oxynitride sintered body, which is light in weight and has a pore size as intended by using a low melting point composition powder.n n n The present invention for achieving the above object, in the method for producing a porous silicon oxide sintered body, Si 3 N 4 : 11-16% by weight, AlN: 3-5% by weight, Al 2 O 3 ; 35-45 weight %, Y 2 O 3 : 35-45% by weight of low melting point powder is mixed and agglomerated, and this blocky low melting point powder is Si 3 N 4 : 57-100% by weight, Al 2 O 3 ; 0-9 A porous silicon oxynitride sintered body formed by adding 10-25% by weight to a β-sialon silicon oxynitride powder having a weight% and an AlN: 0-33% by weight, followed by sintering at a temperature of 1600-1700 ° C. for 1-8 hours The thing regarding a manufacturing method shall be the summary. |
