High-strength ceramic chopsticks and preparation technology thereof

Abstract

The invention provides high-strength ceramic chopsticks and a preparation technology thereof. Each high-strength ceramic chopstick comprises a chopstick blank body and glaze, wherein the chopstick blank body is prepared from the following raw materials in parts by weight: 15 to 22 parts of potassium feldspar, 20 to 25 parts of vermiculite powder, 45 to 53 parts of quartz, 12 to 15 parts of serpentine, 5 to 8 parts of shale, 6 to 10 parts of amphibole, 3 to 5 parts of medical stone powder, 2 to 4 parts of Kanuma soil, 5 to 7 parts of lanthanum oxide, 1 to 3 parts of calcium nitride and 2 to 5 parts of magnesium carbonate; the glaze is prepared from the following raw materials in parts by weight: 35 to 42 parts of transparent frit, 10 to 15 parts of red halloysite, 25 to 30 parts of Dehua quartz, 12 to 18 parts of sodium feldspar, 8 to 12 parts of dolomite, 5 to 8 parts of lepidolite, 3 to 5 parts of molybdenum ore powder, 4 to 6 parts of phosphorus slag powder, 5 to 7 parts of volcanic soil and 1 to 3 parts of a dispersant; the transparent frit is prepared from the following chemical components in percentage by mass: 42 percent to 48 percent of SiO2, 17 percent to 23 percent of Al2O3, 2 percent to 3 percent of K2O, 5 percent to 8 percent of Na2O, 8.6 percent to 9.8 percent of MgO, 5.6 percent to 6.4 percent of Fe2O3, 2.2 percent to 4.6 percent of Ca3N2, 1.5 percent to 2.8 percent of Dy2O3, 3 percent to 3.7 percent of La2O3 and 1.2 percent to 2.6 percent of CaF2.

Description

technical field [0001] The invention relates to the field of preparation of ceramic chopsticks, in particular to high-strength ceramic chopsticks and a preparation process thereof. Background technique [0002] Daily-use ceramics (also refers to tableware or home porcelain), as the name implies: porcelain that is indispensable in people's daily life. The production of daily-use ceramics can be said to be due to people's needs for daily life.
