Problems solved by technology

[0003] However, the heat resistance of the existing pottery products cannot meet the demand, and cracks will appear in the pottery during the high-temperature heating process. Therefore, when the finished pottery is used for heating and cooking with an open fire, the cracks will be further reflected. , leading to a decrease in the service life of the finished pottery, so the present invention proposes a heat-resistant pottery and its manufacturing method

Abstract

The invention discloses a heat-resistant pottery. The heat-resistant pottery comprises the following components in percentage by weight: 46-49.5% of silicon dioxide, 35.5-38.5% of aluminum oxide, 0-5%of ferric oxide, 0-2% of calcium oxide, 0-2% of magnesium oxide, 0.8-1.8% of potassium oxide, 0-1.5% of sodium oxide, 0-2% of titanium dioxide and 7-9% of ignition loss parts. The invention also discloses a manufacturing method of the heat-resistant pottery. According to the heat-resistant pottery manufactured by the manufacturing method, aluminum oxide and silicon dioxide in a pottery blank aremutually combined during high-temperature firing at 1145-1230 DEG C to generate mullite with thermal stability, so that thermal stability of the product after firing is improved, the pottery finishedproduct can be used for cooking by open fire heating, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of pottery, in particular to heat-resistant pottery and a manufacturing method thereof. Background technique [0002] Pottery is a utensil made of clay or clay that is kneaded and then fired. [0003] However, the heat resistance of the existing pottery products cannot meet the demand, and cracks will appear in the pottery during the high-temperature heating process, so when the finished pottery is used for heating and cooking with an open fire, the cracks will be further reflected. , leading to a decrease in the service life of the finished pottery, so the present invention proposes a heat-resistant pottery and a manufacturing method thereof. Contents of the invention [0004] The object of the present invention is to provide a heat-resistant pottery manufacturing method to solve the problems raised in the above-mentioned background technology. [0005] To achieve the above object, the present invention provides ...
