Abstract
The crystallization of a crystalline silicate product from an crystallization mixture is monitored by measuring the specific electrical conductivity of the mixture. The crystallization of metallosilicates, such as aluminosilicate zeolites, may be monitored in this way. Measurement of the electrical conductivity of the crystallization mixture may be carried out on line in a batch or continuous crystallization process. In a continuous process the conductivity may be monitored and used to control the crystallization process parameters in order to achieve a desired degree of crystallinity in the product.
