title: [Adherence of porcelain and metal after firing in H2. 1. Dental porcelain and nickel-chromium alloy].
abstract: The materials for porcelain fusing used in this study were nickel-chromium alloy and ceramco opaque porcelain. The opaque porcelain was fused on the metal surface firing in routine method and in H2. And, the shearing test, X-ray diffraction and quantative analysis of O2 were done. The strengths of the specimens firing in H2 were larger than those of ones firing in routine method. We found that SnO2 of porcelain changed into Sn after firing in H2.
