前言可溶性硅酸盐(这里主要指的是碱金属硅酸盐)在国内外作为商品已经有一百多年的历史了。通过大量的研究工作使得今天人们对这个复杂的水溶胶体系已经有了比较清晰的认识。一般地说,最有商业意义的可溶性硅酸盐是模数 n=3.2～3.3的钠的硅酸盐,也称之为水玻璃。水玻璃溶液以及其他的绝大部分可溶性 Introduction Soluble silicates (mainly referred to here as alkali metal silicates) have been used as commodities for more than one hundred years at home and abroad. Through a large amount of research work, people now have a relatively clear understanding of this complex hydrosol system. In general, the most commercially-available soluble silicates are sodium silicates with modulus n = 3.2 to 3.3, also known as water glass. Water glass solution and most other soluble
