| titleOfInvention | Y with ultrahigh porosity and low blank shrinkage2SiO5Preparation method of porous ceramic |
| abstract | The invention relates to the field of thermal protection materials, in particular to a material with ultrahigh porosity and low blank shrinkage Y 2 SiO 5 A preparation method of porous ceramics. Using yttrium oxide and silicon oxide powder as reactants, using water as a dispersion medium, adding a dispersing agent, continuously stirring to prepare ceramic slurry, heating the slurry, adding a foaming agent, quickly and mechanically stirring to foam, adding gelatin and a surfactant, then performing injection molding and low-temperature freezing, then performing vacuum drying, demolding a blank, drying in an oven, and preparing Y through high-temperature sintering 2 SiO 5 A porous ceramic. The invention solves the problem that the shrinkage rate of the blank is very large or the deformation is serious during demoulding and drying, and synthesizes the Y with ultrahigh porosity, low density, low thermal conductivity and high temperature resistance 2 SiO 5 The porous ceramic has wide application prospect in the field of thermal protection materials. The method has low cost and strong operability, can prepare the porous material with ultrahigh pores (96 percent) by adopting a novel and simple production process, and has wide industrial production prospect. |
