    In reality, in a kiln burning a normal cement rawmix, decomposition begins at around 650°C. This, put simply, is because the clay components (or their decomposition products) act as an acid. The reaction is: 2 CaCO 3 + SiO 2 → Ca 2 SiO 4 + 2 CO 2. The product of the reaction is "incipient belite" so called because the early reaction products are "amorphous", and not identifiable as
