The present invention relates to a high-porosity porous ceramics prepared from expandable hollow microspheres and a polymer ceramic precursor, characterized in that the porosity is 60% or more and the pore density is 10 9 pieces / cm 3 or more, and the polymer ceramic precursor Uniformly mixing the powder with the expandable hollow microspheres and the ceramic powder, or uniformly mixing the polymer ceramic precursor powder and the expandable hollow microspheres to form a molded body; Heating and expanding the molded body; Curing the expanded molded article; It provides a high porosity porous ceramics and a method for manufacturing the same, which are formed from the expanded hollow microspheres and the polymer ceramic precursor, characterized in that the step of pyrolysis by heating the cured molded body.n n n As described above, the present invention has a higher porosity and higher pore density than conventional porous ceramics, and thus, various high temperature structural materials, high temperature furnace fixtures, bulletproof materials, impact absorbing materials, heat insulating materials, refractory materials, and light weights. There is an effect that can be applied to suit the field such as structural materials. |
