Abstract
A dental material consists of an unfired mixture of 30-70% of reinforcing refractory particles sized between <200m and <10m , of titania, alumina, zirconia, singly or together, with a matrix forming material felspar, borosilicate glass dental porcelain. The is shaped fired at 850-1400 DEG C. in air vacuo to fuse the without affecting reinforcing material. GB39709>Download PDF in English
