example 1

[0023] Mix the animal bone ash and polyvinylpyrrolidone into the ball mill jar according to the mass ratio of 5:1, and add zirconia ball milling beads according to the mass ratio of the ball to material at 30:1. After ball milling and mixing for 6 hours, the material is discharged and passed through a 325-mesh sieve. The ball mill was obtained, and then the obtained ball mill and the ethanol solution with a mass fraction of 60% were mixed at a mass ratio of 1:50, and the temperature was 50°C, and the ultrasonic frequency was 60kHz, and the temperature was ultrasonically dispersed for 60 minutes to obtain a dispersion. Then use citric acid solution with a mass fraction of 10% to adjust the pH of the dispersion to 6.2 to obtain a weakly acidic dispersion; in parts by weight, take 100 parts of weakly acidic dispersion and 40 parts of ethyl orthosilicate successively, and first Add the acidic dispersion into a four-necked flask with a stirrer, adjust the stirring speed to 600r / min,...

Abstract

The invention discloses a thermal shock resisting bone-china preform body and belongs to the technical field of ceramic materials. The thermal shock resisting bone-china preform body developed in theinvention is prepared by sintering bone meal, clay and chinastone. A preparation method comprises the following steps: firstly, performing ball-mill mixing on animal bone ash and polyvinylpyrrolidone,sieving, dispersing a mixture into an ethanol solution and adjusting the pH value to weak acidity to prepare a weak acidic dispersion solution; subsequently, dropwise adding tetraethylortho silicateinto the weak acidic dispersion solution; after adding is finished, continuously carrying out stirring reaction for 2 to 4 hours, filtering, washing and drying to obtain the bone meal; secondly, carrying out ball-mill mixing on the bone meal, the chinastone and water, successively allowing standing still, aging, and carrying out slip casting and dry fettling to obtain a bone-china preform body; thirdly, sintering the bone-china preform body in an electric furnace and cooling to obtain the thermal shock resisting bone-china preform body. The thermal shock resisting bone-china preform body obtained in the invention has excellent thermal shock resistance and whiteness.

Description

technical field [0001] The invention discloses a heat-shock-resistant bone china blank, which belongs to the technical field of ceramic materials. Background technique [0002] Bone china is a kind of high-grade porcelain. Because of its high whiteness, good transparency, fine porcelain quality, and bright and smooth glaze, it is known as "thin as paper, white as jade, bright as a mirror, and sound like a chime". Bone china is a kind of soft porcelain that is mainly made of animal bone ashes, and some mineral materials such as clay, feldspar, and quartz are added at the same time, and is fired by high-temperature bisque firing and low-temperature glaze firing. The phase composition of the porcelain body is mainly tricalcium phosphate, anorthite and a certain amount of glass phase. Bone china tea sets and coffee sets have become ideal appliances for companies of all sizes and wealthy families, and they are also the best gifts for relatives and friends. Bone China has become...
