Abstract

The invention provides a ceramic plate, and belongs to the field of ceramics. The ceramic plate comprises a plate and a glaze; the plate comprises the following components, in parts by weight: 15-25 parts of kaolin, 5-15 parts of talc powder, 0.5-1.5 parts of polyvinyl alcohol, 0.2-0.5 part of citric acid, 25-35 parts of cordierite, 2-4 parts of beryllium oxide, 3-5 parts of beryllium hydroxide, and 5-10 parts of strontium carbonate; and the glaze comprises the following components, in parts by weight: 65-75 parts of petalite, 5-15 parts of potassium feldspar, 4-6 parts of zinc oxide, 4-6 parts of kaolin, 6-8 parts of burnt talc, 2-4 parts of lithium carbonate, 2-4 parts of pyrochlore, 2-5 parts of spinel, and 0.5-1.5 parts of bismuth iron molybdenum oxide. The ceramic plate provided by the invention has good heat resistance and high strength and is not easy to deform.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a ceramic plate. Background technique [0002] The panel of the induction cooker has high requirements on the heat resistance and expansion coefficient of the material. The glass-ceramic plate is the main choice of the induction cooker panel on the market now, and its performance is better. The advantage of the glass-ceramic plate is that it has good heat resistance, a small expansion coefficient, and no water seepage. However, the glass-ceramic plate has a high melting point and low strength. It cannot be polished by mechanized and automatic methods in the production process. It can only be processed by semi-mechanized or pure manual processing. Therefore, its price is generally relatively high, resulting in a higher price for induction cookers. [0003] Therefore, people hope to use cheap ceramic plate to replace. However, the existing heat-resistant ceramic plates have a relatively ...
