Specification: 3.2mm,3.35mm,3.5m
Note: packaging and specifications can be availiable according to user’needs.
Quality traits: Usual Sodium silicate is slightly light-colored solid block or granule, it will become a transparent or semi-transparent slightly color viscous fluid after High temperature and high pressure solution.
Molecular formula: Na2O·mSiO2. The molar ratio meaning the proportion of quartz and alkali silica determine the modulus M. the modulus indicates the composition of the sodium silicate and affects the physical and chemical properties. So sodium with different modules have different usages. It is used widly in ordinary casting,precising casting,paper making,pottery ,clay, mill run, kaolin, abstersion and many other fields.
