Highly Porous Ceramics Fabricated From Preceramic Polymers And Expandable Microspheres, And The Producing Method The Same

摘要

The present invention is a porosity of 60% or more, the pore density of 10 ⁹ / inflatable hollow fine, characterized in that at least ㎤ sphere and is made from a polymeric ceramic precursor on the porosity of the porous ceramics and a manufacturing method, the polymeric ceramic precursor powder and expandable hollow microspheres and ceramic powder are uniformly mixed with or, to prepare a polymeric ceramic precursor powder and expandable hollow microspheres are uniformly mixed and molded with it a shaped body; And the step of expansion by heating the formed article; And curing the inflatable shaped body; And is made from expandable hollow micro-sphere polymer ceramic precursor, characterized in that consisting of the steps of thermal decomposition by heating the hardened molded article provides a porosity of the porous ceramics and a manufacturing method thereof.; Thus, the present invention has a high porosity as compared with conventional porous sera miss material, the pore density is high, for various high-temperature structural material, the jig for the hot (Kiln Furniture), bullet-proof materials, shock absorbing material, heat insulating material, refractory, light-weight there is an effect that can be used with proper application in the field of structural materials and the like.
