摘要： A thin ceramic plate which is a ceramic plate consisting of a multilayered calcined sheet with at least a 3-layer construction comprising a ceramic material as the major component, wherein the majority of the layers of the layered construction have a layer thickness of 0.05-3 mm and have substantially different ceramic material compositions, with at least one pair of adjacent layers having thermal expansion coefficients adjusted to differ by no more than 2 x 10 -6 /°C.
Even at low thicknesses of 2-10 mm and large-sized dimensions of 100 cm and greater, such plates have excellent properties, including virtually no warping or other deformity, excellent flatness, water absorption of 0.5-10% and flexural strength of 350 kg/cm 2 or greater.
The thin ceramic plate has high industrial value since it may be applied for a wide range of uses, including interior and exterior building materials, flooring materials, furniture, household goods such as wash-stand counters and kitchen utensils, top plates and counters for testing benches, various interior goods, materials for civil engineering such as inner panels for tunnels, for tourism-related purposes such as guide boards and signboards, and artistic painting.
