Extract

Although differential thermal analysis can now be used to assess the complete constitution of clays and many ceramic materials the silica minerals present many unusual difficulties. The importance of silica and siliceous materials for refractory purposes, the changes which take place in such materials on firing, and the influence of the constitution on the properties of the final product, necessitate a rapid and reliable method for the identification and estimation of the silica phases. Chemical methods cannot differentiate between the various types. X-ray analysis although useful for identification purposes, cannot as yet be used for estimation of the three phases, when all are present together.
