Metasilicate was listed as one of the "priority development of fine chemicals" and "the future of inorganic chemical products, the focus of development." A salt of sodium silicate partial. Metasilicate ordinary bulbs and caustic alkali hydrothermal reaction and obtained low molecular crystals, commodity anhydrous, five and nine water hydrates, nine hydrates exist only on the Chinese market, in the 1980s urgent need metasilicate and hastily developed low-tech emergency products, because the melting point of only 42 ℃, it is easy to become liquid or paste during storage, are gradually being phased out, but due to some user habits and some areas of the crystalline water is not very concerned about, nine water partial sodium or have a certain market.
