Embodiment 1

[0041]45% kaolin, 22% calcined kaolin, 20% quartz, 3% zirconium dioxide, 5% calcined talc, 5% bone ash, 0.3% each of cerium oxide and lanthanum oxide (both industrially pure, the same below), the total amount is 100.6, The ingredients are put into the mill, material: ball: water = 1: 2.5: 0.5, pass through 220 mesh to remove iron, sieve, stale, press, mud, stale and then grouting or roll forming can be dried and glazed at 1200 ° C ~ 1230 ° C ℃ firing.

Embodiment 2

[0043] 20% kaolin, 35% calcined kaolin, 33% quartz, 10% zirconium dioxide, 1% calcined talc, 1% bone ash, 0.2% each of cerium oxide and lanthanum oxide, total 100.4, ingredients into the mill, material: ball: water =1:2.5:0.5 Pass through 220 mesh to remove iron, sieve, stale, press, knead mud, stale and then grout or roll forming, then dry and apply glaze, and fire at 1200℃~1230℃.

[0044] It can be verified by the above two examples that the present invention not only reduces the firing temperature of strengthened porcelain from 1380°C to 1420°C to 1200°C to 1230°C, but also reduces the firing cost by about 40% and increases the output by 30%. High-white low-temperature strengthened porcelain with a whiteness of not less than 80 degrees and a strength of not less than 180Mpa can be obtained.

Abstract

The invention relates to the field of daily fine porcelains, in particular to a high-whiteness strengthened low-temperature fired daily fine porcelain and a manufacturing method thereof. A blank of the daily fine porcelain comprises the following components in percentage by weight: 50 to 75 percent of SiO2, 15 to 30 percent of Al2O3, 0.3 to 1.5 percent of MgO, 0.4 to 2.0 percent of P2O5, 3 to 10 percent of ZrO2, 0.2 to 0.3 percent of CeO2 and 0.2 to 0.3 percent of LaO2. Compared with the prior art, the high-whiteness strengthened low-temperature fired daily fine porcelain and the manufacturing method thereof can make the firing temperature of the strengthened porcelain reduced from the temperature of between 1,380 and 1,420 DEG C to the temperature of between 1,200 and 1,230 DEG C, also can reduce the firing cost by about 40 percent and improve the yield by over 30 percent; and the whiteness of the product is more than 80 degrees, and the strength is 180 MPa.

Description

technical field [0001] The invention relates to the field of daily-use fine porcelain, in particular to a daily-use fine porcelain with high whitening strength and low-temperature firing and a manufacturing method thereof. Background technique [0002] At present, α-Al is used in the production of reinforced porcelain 2 o 3 Firing at 1380°C ~ 1420°C, as recorded in the first issue of the thirty-sixth volume of "Chinese Ceramics", "Research and development of high-alumina reinforced daily-use porcelain", and as in the third issue of the twenty-sixth volume of "Hebei Ceramics" According to the "Research and Development of α-Crystobalite Reinforced Porcelain", the strength of the reinforced porcelain produced by it is about 120Mpa, and the whiteness is about 70 degrees. Due to the high-alumina formula, the firing time is long, the energy consumption is high, the yield rate is low, and the kiln The high consumption of tools restricts the popularization and development of high-...
