Study on Effect of Lattice Distortion on Infrared Properties of Ceramic Tiles at Ambient Temperature
Effect of the lattice distortion of the main crystal mullite, addition of copper mine tailing and the firing schedule on the infrared properties were studied. The study revealed that the higher lattice distortion is, the higher infrared emissivity of ceramic tiles is. The addition of raw materials containing iron and other elemental impurities could form the solid solution in the body what promote the degree of lattice distortion of main crystal which affects the infrared emissivity of the ceramic tiles. With the increasing of firing temperature, the degree of lattice distortion of main crystals will decrease and the infrared properties also decrease.
