More Information
Summary:The prod. is durable, light to medium weight, and of high strength. The basic ingredient may be flue dust but it has to comprise a large portion of SiO2 and Al2O3, the active reagent is added in the form of lime and the mixture is being stirred at 75-105 deg.C for 2 days in a steam atmos. The reaction can be activated by acids (H2SiF6, HF, (COOH)2).
