摘要：

A method for pore-size control was found for porous glass-ceramics with a skeleton of CaTi4(PO4)6. The pore size was increased by applying a post crystallization heat treatment and subsequent acid leaching. The median pore diameter was controllable in the range 40-150 nm by changing temperatures of the heat treatment. The mechanism is due to the formation of leachable calcium pyrophosphate at the boundary between interlocking CaTi4(PO4)6 and Ca3(PO4)2 phases constituting the glass-ceramics before leaching.
