    摘要: A low-fusing temperature porcelain compositions, methods of use thereof on metal or porcelain substrates to form dental prostheses and kits therefor. Compositions of the invention have a fusing temperature of less than 800.degree. 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 SiO.sub.2, from 6 to 12 percent by weight Al.sub.2 O.sub.3, from 6 to 12 percent by weight Na.sub.2 O, from 5.5 to 10.50 percent by weight K.sub.2 O, from 1 to 3 percent by weight Li.sub.2 O, from 0.8 to 2.5 percent by weight CaO, from 0.8 to 4.0 percent by weight B.sub.2 O.sub.3 and from 0.1 to 0.8 percent by weight CeO.sub.2.
