LOW-FUSING TEMPERATURE PORCELAIN, COMPOSITIONS, PROSTHESES, METHODS AND KITS |
摘要 |
Low-fusing temperature porcelain compositions, methods of use therof on metal or ceramic substrates to form dental prostheses and kits therefor. Compositions of the invention have a fusing temperature of less than 800 DEG C and a coefficient of thermal expansion compatible with a substrate of metal or ceramic. Each composition includes, in weight percent of the composition, from 40 to 65 percent by weight SiO2, from 6 to 12 percent by weight Al2O3, from 6 to 12 percent by weight Na2O, from 5.5 to 10.50 percent by weight K2O, from 1 to 3 percent by weight Li2O, from 0.8 to 2.5 percent by weight CaO, from 0.8 to 4.0 percent by weight B2O3 and from 0.1 to 0.8 percent by weight CeO2. |
