Porous Glass Ceramic Bioimplants

Glass and Ceramics, 2000
A technology for producing porous glass ceramic implants has been developed using foam polyurethane as the burning-out forming matrix. Porous glass ceramics with pore sizes of 300 – 500 and 600 – 700 μm were obtained. Sanitary-chemical, toxicological-hygienic, and medicobiological tests were carried out.
