Cordierite is a popular magnesia-alumina-silica ceramic used in various kinds of industrial applications. It is used, for example, as a carrier for catalysts in the automotive industry. During the production of this ceramic, various raw materials are ground and mixed to form a green body. During firing under oxidizing atmospheres, the organic additives are burned out and the cordierite phase is formed at high temperatures. Using the DIL 402 PC in combination with the c-DTA® software, the production process can be analyzed in detail.
