Bauxite - dt-ref

This process of calcining (heating) bauxite in kilns removes moisture and gives Calcined Bauxite its high alumina content and refractoriness, low iron oxide, and grain hardness and toughness. Its thermal stability, high mechanical strength and resistance to molten slags make Calcined Bauxite an ideal raw material in the production of many refractory, abrasive and specialty product applications.

Cement clinker - Wikipedia

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

Vapour pressures were studied over a wide temperature range. Anhydrite alone produced a partial pressure of 20 kPa at 1455°C, whereas addition of silica reduced this to 1135°C, and addition of kaolin reduced it to 986°C. The situation is entirely analogous. Clearly, the presence of clay minerals in a cement kiln increases the CO 2 partial pressure. A typical decomposition pressure of calcite in the presence of microcrystalline clay …
