A kind of sintered carrier and its manufacturing method

Abstract

The invention relates to a sintering supporting body which is prepared from mullite, aluminum powder, activated alumina, kaolin, quartz, cordierite, magnesite powder, talcum powder, dextrin, lithium manganate, lithium iron phosphate, lithium cobaltate and a micropore agent. The invention is characterized in that the sintering supporting body is prepared from the following components in parts by weight: 10-25 parts of mullite, 15-30 parts of aluminum powder, 5-15 parts of kaolin, 15-20 parts of cordierite, 3-8 parts of magnesite powder, 3-10 parts of talcum powder, 2-8 parts of activated alumina, 30-50 parts of quartz, 6-12 parts of dextrin, 2-5 parts of lithium manganate, 2-5 parts of lithium iron phosphate, 3-8 parts of lithium cobaltate and 10-15 parts of micropore agent. The sintering supporting body has the advantages of simple processing technique, accessible raw materials and long service life, and the number of repeated uses can reach 50 or above. The sintering supporting body has high thermal shock resistance, and can not influence the chemical reaction and crystallization recombination of the sintered substance in the sintering process. The sintering supporting body also has the advantages of high corrosion resistance, environment friendliness, high safety, high strength and low breaking and powder shedding tendency, and can be widely used as a supporting body in the sintering process.

Description

technical field [0001] The invention relates to a refractory material, in particular to a carrier used for sintering during calcination and a manufacturing method thereof. Background technique [0002] At present, there are many products made of new materials, and their application fields are also very wide. For example, battery products and some assembly parts used in the manufacture of mobile phones, computers and automobiles must be calcined. The current sintering carrier is a sagger, and its processing ingredients are made of general refractory materials. Its disadvantage is that it has low strength and will be broken after 3-4 times of use. The burning material reacts, which seriously affects the quality of the burning material. Furthermore, the porosity is low, the weight of the bowl, and the heating of the burning material is uneven, so it cannot meet the requirements of current high-tech products. Therefore, through our years of research, A carrier body suitable for...

The current sintering carrier is a sagger, and its processing ingredients are made of general refractory materials. Its disadvantage is that it has low strength and will be broken after 3-4 times of use. The burning material reacts, which seriously affects the quality of the burning material. Furthermore, the porosity is low, the weight of the bowl, and the heating of the burning material is uneven, so it cannot meet the requirements of current high-tech products. Therefore, through our years of research, Developed a carrier suitable for sintering in the process of making new material products, so that the sintered carrier and the fired object can set off each other during the calcination process, improving the quality of the fired object
