Embodiment 1

[0013] The lithium-magnesium ceramic bowl is composed of a green body and an enamel layer. The raw material weight percentage of the green body ingredients is: 76% talc, 13.5% kaolin, 7% feldspar, 2% spodumene, 2% additives, The plastic adhesive is 0.5%; the raw material weight percent of the enamel layer ingredients is composed of 46% feldspar, 25% quartz, 14% talc, 10% kaolin, 2.5% zinc oxide and 2.5% additives. Make the green body and enamel separately, measure the moisture content of the raw materials when making the green body, and then weigh various raw materials according to the weight percentage of the raw materials used in the green body ingredients, put the raw materials in a ball mill, mix and ball mill for 25-30 hours to the desired Fineness, put it into the pulp tank and stir evenly, then sieve, remove iron, squeeze mud, rough smelt, stale, scouring, roll forming, drying, trimming, and make the green body; according to the ingredients used in the enamel layer Raw ...

Abstract

The invention belongs to the technical field of porcelain and relates to Mg-Li porcelain and its production method. The Mg-Li porcelain is composed of a base substrate and an enamel layer. The base substrate comprises the following chemical ingredients of: by weight, 5-10% of Al2O3, 60-70% of SiO2, 0.1-0.3% of Fe2O3, 1-2% of CaO, 18-24% of MgO and 1-3% of KNaO. The enamel layer comprises the following chemical ingredients of: by weight, 10-15% of Al2O3, 65-75% of SiO2, Fe2O3 being less than 0.2%, 1-4% of CaO, 2-5% OF MgO, 2-5% of ZnO and 4-7% of KNaO. Sintering temperature range is controlled within 1240-1270 DEG C and the sintering time is 15-18 hours. According to the invention, the production condition is moderate. By the adoption of the production method, plasticity of a mud material is raised, its moulding performance is good, and the sintering temperature is low. The product has advantages of high whiteness, good light transmittance, high intensity and good thermal stability, and is easy to realize industrial popularization.

Description

technical field [0001] The invention belongs to the technical field of daily-use ceramics, and in particular relates to a ceramic product and a production method thereof, in particular to a lithium-magnesium porcelain and a production method thereof. Background technique [0002] Talc porcelain is a high-grade daily-use porcelain. As early as the 18th century, Britain used talc as the main raw material to make talc porcelain. Talc is a hydrous silicate mineral of magnesium, so talc porcelain is also called magnesium porcelain. Talc porcelain (magnesia porcelain) is characterized by fine and milky porcelain, thin body translucent, fat luster, and greasy feeling to the touch. Magnesia porcelain has a flaky structure, which is easy to flake when broken, and is not easy to crush. In the process of manufacturing talc porcelain, there are phenomena such as difficult forming, high temperature deformation, poor firing performance, and easy porcelain explosion. Therefore, the product...
