SODIUM SILICATE SOLID, also named WATER GLASS MOLECULAR FORMULA: Na2O• MSiO2, "m"is modulus(mol ratio between SiO2 and Na2O) APPEARANCE: It is light blue molded lumps with crystal characteristic or granular solid. CHARACTERSTIC & USAGE: Details see the characteristic and usage of sodium silicate liquid. INTRODUCTION: QDSS is one of main constitutor of state standard for sodium silicate, its sodium silicate was approved as FAMOUS BRAND OF QINGDAO. We can produce it accoring to the requirements of costomers, such like requirements for MODULUS, CONTENT, Al2O3, Fe2O3 and so on. It's sodium silicate won lots of reputation form mainland (China) and other foreign countries. Especially, the high purity sodium silicate solid was successfully trial-manufactured by QDSS. It's lumpish, clear cullet with cone appearance. It can be used only when it is dissolved and become liquid sodium silicate.
