dilithium metasilicate - Nature
Open Data Verified Data
odorless, tasteless transparent liquid. It is weakly alkaline, and the pH value is about 11. The relative density and viscosity of the product vary with the product type, and the relative density is between 1. 16 and 1. 19 (25 ℃). Soluble in water and alkaline solution, insoluble in alcohol and organic solvents. And acid free gel. It is self-drying, and after the evaporation of the water in the solution, a water-insoluble dry film can be formed, which has water irreversibility.
