The use of a process for the preparation of porous biocompatible glasses or glass-ceramics

摘要

The use of a method, in the known basic materials for biocompatible or bioactive glasses or glass-ceramics melted, broken or pulverized fed to an extruder, in this to - or melted and, at the same time, foaming agents are added and the foaming agent is metered by the pressure built up are introduced into the glass melt, and this in the subsequent pressure reduction foaming, for the production of open - or closed-pore biocompatible or bioactive glasses or glass-ceramics.
