本文回顾和综述1933——1979年间对SnO-SiO_2系状态图的认识过程。 1933年德国冶金学家Keysselitz和Kohlmeyer研究的SnO-SiO_2系状态图(图-1)问世以来,冶金及硅酸盐文献书籍中很少引用,甚至长期对之持怀疑态度。这大概是因为该状态图未反映出一般MeO-SiO_2(或M_2O-SiO_2)状态图上 This article reviews and summarizes the process of understanding the state diagram of SnO-SiO 2 system from 1933 to 1979. The metallurgical and silicate literature has rarely been cited in the literature of 1933, even skeptical of the long-term, since the advent of the state-of-the-art SnO-SiO 2 system by Germany’s metallurgist Keysselitz and Kohlmeyer in 1933 (Fig. This is probably because the state diagram does not reflect the general state diagram of MeO-SiO 2 (or M 2 O-SiO 2)
