Abstract

The invention discloses a breaking-resistant shadow blue glaze porcelain bowl and a preparation method thereof, belonging to the porcelain bowl manufacturing field. The porcelain bowl comprises ground glaze, cover glaze and a preform body, wherein the ground glaze is prepared from the following chemical components: SiO2, Al2O3, CaO, K2O, Na2O, MnO2, B2O3, MgO and Li2O; the cover glaze is prepared from the following chemical components: SiO2, Fe2O3, ZnO, CaO, B2O3, K2O, Na2O, TiO2, BaO and MgO; and the preform body is prepared from the following raw materials: clay produced in Datong, Shanxi, attapulgite clay, purple sand, spodumene, hsianghualite, polypropylene, carbon fiber, cobalt oxide, zirconium oxide and polyethylene oxide. The preparation method comprises the steps of putting a preform body raw material into a ball grinder so as to be subjected to ball-milling firstly, then adopting a slurry ejection or plastic pressing flow compression method to prepare a semi-finished product, adding the ground glaze and the cover glaze on the semi-finished product by using a glaze dipping or glaze pouring method after bisque firing, and finally roasting again. The shadow blue glaze porcelain bowl is gentle in color and luster, excellent in texture, strong in heat-insulating property, high in mechanical strength, nonhazardous and non-residual, and does not cause harm to a human body.

Description

technical field [0001] The invention belongs to the field of porcelain bowl manufacture, and in particular relates to a shadow-resistant blue-glazed ceramic bowl and a preparation method thereof. Background technique [0002] Ceramic bowls are a large category of ceramic tableware. The traditional concept of ceramics refers to all artificial industrial products that use inorganic non-metallic minerals such as clay as raw materials. It includes various products made of clay or a mixture containing clay through kneading, shaping, and calcination. The firing and application of ceramic tableware has a long history in our country. Its various shapes, colorful colors, cool and smooth feel, easy to wash, are deeply loved by Chinese people. However, some physical and chemical performance indicators of porcelain tableware are insufficient at present, such as easy qualitative change, odor, excessive dissolution of trace elements and other factors that are not conducive to human healt...
