IPC: C04B41/87
Filed: 1989-10-25
Abstract: PURPOSE:To obtain a far infrared radiator of good appearance which will not cause peeling of a coating layer even in use over a long period by applying to the surface of a base made from a low-expansion crystallized glass of Li2O- Al2O3-SiO2 type a ceramics coating material of high far-infrared emissivity to which crushed material of the same type as the base is added, and baking the coating material at high temperature less than the softening point of the base. CONSTITUTION:A far infrared radiating ceramics coating material such as ZrO2 is applied to the surface of a base made from a crystallized glass of low thermal expansion such as a crystallized glass of Li2O-Al2O3-SiO2 type. Addition of crushed material of the same type as the base to the ceramics coating material causes the coefficient of thermal expansion of the ceramics coating layer and that of the base to approximate to each other, and during baking a reaction occurs between both of them so that a chemically strong junction is obtained. A mixture consisting of pigment and infrared radiation ceramics which is temporarily burned in advance at temperatures higher than that for baking is used to prevent variation in color tone during subsequent baking process and its actual use thereafter.
