Problems solved by technology

However, compared with traditional high-temperature porcelain, daily-use fine porcelain also has its shortcomings. First, the hardness of the carcass is relatively poor, and the porcelain mouth is easy to produce gaps when the product is used for a long time; When in use, the product is prone to bursting

Abstract

The invention discloses daily-use fine porcelain and a preparation method thereof. The daily-use fine porcelain comprises the following raw materials of: in percent by mass, 50-55% of bone charcoal, 20-30% of kaolin, 10-20% of feldspar and 5-15% of quartz, the sum of the components is unity, and then a nanofiber additive which accounts for 5-10% of the total mass of the raw materials is added intothe raw materials. The daily-use fine porcelain is green low-carbon, and has high hardness and good thermal stability.

Description

technical field [0001] The invention relates to daily-use fine porcelain and a preparation method thereof, belonging to the field of inorganic non-metallic materials (ceramics). Background technique [0002] At present, daily-use fine porcelain has been used by nobles in various countries for a long time, and it is currently recognized as a high-grade porcelain in the world. Because of its "thin as paper, transparent as a mirror, sound like a chime, and white as jade", the porcelain is fine and transparent, the shape is beautiful and elegant, the color surface is moist and bright, and the flower surface is colorful, which makes it white and luxurious. The shape of the porcelain has the dual value of use and art. In history, it is a treasure for the court and aristocratic collections. It is a symbol of power and status. It is known as the "King of Porcelain". With its high quality, high style and high taste, daily-use fine porcelain has become the must-choice porcelain for s...
