Preparation and property of porous calcium silicate ceramic by two-step ultrafast high-temperature sintering
Porous calcium silicate ceramic has been prepared by ultrafast high-temperature process in several minutes. The effect of sintering current and starch content on the phase composition, pore structure, compressive strength, and air permeability have been investigated. Homogeneous pores can be formed during the fast decomposition of calcium silicate hydrate, calcium carbonate, and starch. The optimized composition shows the high compressive strength (over 7 MPa), porosity (60.8%), and air permeability (379.4 L/m2 s). Results showed that the ultrafast high-temperature sintering method can achieve homogenous porous structure in much shorter time than conventional furnace sintering.
