Problems solved by technology

However, daily-use feldspar porcelain also has its disadvantages compared with traditional high-temperature porcelain. 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 hot, the product is prone to bursting

Abstract

The invention discloses a medium-low-temperature daily-use feldspar porcelain preparation method, wherein the raw materials comprise, by mass, 40% of bone carbon, 25% of kaolin, 10% of feldspar, 13% of quartz, 12% of talc, and 9% of calcium sulfate nanometer fiber. The preparation method comprises: selecting raw materials, crushing, matching the materials, carrying out dry powder ball milling, adding calcium sulfate nanometer fiber, detecting the fineness, adjusting the slurry, discharging the slurry, screening to remove iron, carrying out pressure filtration mud squeezing, milling the mud, directly molding, drying, carrying out biscuit firing for 8 h to achieve a temperature of 1100-1150 DEG C, carrying out thermal insulation for 30 min, and cooling to obtain a daily-use feldspar porcelain billet. According to the present invention, the production method solves the problems of poor hardness and poor thermal stability of the conventional medium-low-temperature daily-use feldspar porcelain billet, is scientific and reasonable, and has advantages of advanced process technology, easy implementation, high yield, good product quality, substantially shortened firing cycle, reduced firingtemperature, significantly reduced production cost and wide market prospect.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a preparation method of medium-low temperature daily-use feldspar porcelain. Background technique [0002] Daily-use feldspar porcelain has long been used by nobles in various countries, and 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 grade, daily-use feldspar porcelain has become the must-choice...
