Self-foamed Porous Ceramic Compositions and Method for Making Porous Ceramic Using the Same

摘要

The invention of the porous ceramic by then ground to a glass containing a component for generating gas at a high temperature thermal treatment when finely sintered after type foaming self rapidly become very high gajina high porosity strength foamed porous ceramic composition and this, in the composition It relates to a process for producing the same.; Self composition of the present invention in the expanded porous ceramic composition is calcium oxide (CaO) oxide is 43-47% by mole ratio, respectively, of silica (SiO ₂₎ is 43-47%, borate (B ₂ O ₃₎ the 6-14% range It is characterized.; The porous ceramic is a step of producing a glass consisting of CaO, SiO ₂ and B ₂ O _3, and; Pulverizing the glass to a fine powder having an average particle size of 1~10μm and range; And a step of molding the powder in a press; In that it comprises a step of self-firing by heat-treating the molded product at a temperature between 950 ~ 1200 ℃ is obtained according to the production process is characterized.
