Preparation method for reducing firing temperature of Nixing ceramics
The invention discloses a preparation method for reducing the firing temperature of Nixing ceramics. A blank is prepared from the following raw materials in parts by weight: 45 to 55 parts of east clay, 25 to 35 parts of west clay, 1 to 2 parts of bentonite, 1 to 3 parts of wollastonite, 0.1 to 0.3 parts of tremolite, 0.2 to 0.4 parts of powder quartz and 1 to 3 parts of aluminum oxide. The preparation method comprises the following steps: (a) heating to 70 to 90 DEG C at the speed of 25 to 35 DEG C/h, and keeping the temperature for 6 to 8 hours; (b) heating to 120 to 150 DEG C at the speed of 35 to 45 DEG C/h, and keeping the temperature for 2 to 4 hours; (c) heating to 400 to 500 DEG C at the speed of 60 to 80 DEG C/h, and keeping the temperature for 0.2 to 0.4 hours; (d) heating to 700 to 800 DEG C at the speed of 60 to 80 DEG C/h, and keeping the temperature for 0.1 to 0.3 hours; (e) heating to 1,040 to 1,060 DEG C at the speed of 80 to 100 DEG C/h, and keeping the temperature for 0.6 to 0.8 hours.
