METHODS OF DETERMINING THE MINERALOGY OF CALCINED AND FLUX-CALCINED DIATOMITE PRODUCTS

摘要

Products (4) comprising a physical component (6) and Silica Documentation (8), and methods of preparing such products (4) are disclosed. In some embodiments, the physical component (6) may be powdered or in particulate form. The physical component (6) includes diatomite. In such products (4), a crystalline silica content of the physical component (6) by weight is greater as measured according to Traditional Methods than as measured according to a method that differentiates between opal-C and cristobalite. The Silica Documentation (8) discloses the crystalline silica content present in the physical component (6) as measured according to the method that differentiates between opal-C and cristobalite. The method of preparing the product (4) may include analyzing the physical component (6) for crystalline silica content using an LH Method to determine cristobalite content and preparing Silica Documentation (8) based on the results of the LH Method.
