Novel mounting ceramic product and preparation method thereof

Abstract

The invention relates to a novel mounting ceramic product and a preparation method thereof; natural minerals are employed to be main raw material; weight percentage composition of a blank body formula is listed below: 76-78% of burning clay, 8-9% of barium carbonate, 6% of burning talcum, and 8-9% of alumina; compounding, dry method ball milling, screening, granulation, dry-pressing moulding, and burning are carried out to obtain the product; sintering temperature is 1280-1320 DEG C; finish time is 4-8 hours; temperature insulation time is 1 hour; the mounting ceramic is good in thermal conductivity, high in mechanical strength, low in dielectric constant, high in volume resistance, not only saves ceramic raw material in shortage, but also complies with national energy saving and emission reduction policy, thereby having wide application prospect.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), in particular to a ceramic material used in electronic equipment for installation, fixation, support, insulation, isolation and connection of various radio components and devices. Background technique [0002] Device ceramics are insulating ceramics, and there are many types, including alumina ceramics, magnesia ceramics, beryllium oxide ceramics, silicon carbide ceramics, silicon nitride ceramics, aluminum nitride ceramics, mullite ceramics, and so on. Their common features are good thermal conductivity, high mechanical strength, low dielectric constant and high volume resistance and so on. However, there are some deficiencies in these existing device porcelains, such as the small firing range of magnesia porcelain; it is difficult to sinter alumina ceramics; although beryllium oxide ceramics have good thermal conductivity, they are expensive and radioactive; , Carbide...

AI Technical Summary

Problems solved by technology

However, there are some deficiencies in these existing device porcelains, such as the small firing range of magnesia porcelain; it is difficult to sinter alumina ceramics; although beryllium oxide ceramics have good thermal conductivity, they are expensive and radioactive; , Carbide ceramics need to be sintered in a non-oxidizing atmosphere

Therefore, all there is certain defective in the device porcelain of selling on the market at present.
