Abstract
A method of determining opal-C and cristobalite contents of a product that comprises diatomite is disclosed. The method may comprise performing thermal processing to determine a loss on ignition for a representative first portion of a sample of the product; identifying and quantifying primary and secondary peaks present in a first diffraction pattern that results from bulk powder X-ray Diffraction on a representative second portion of the sample; and using a known standard sample of cristobalite to determine whether the primary and secondary peaks present in the first diffraction pattern indicate the presence of opal-C or cristobalite in the product.
