Abstract

The invention relates to a composite oxide glass-ceramic, an insulating dielectric slurry, a preparation method and application thereof, and belongs to the technical field of thick film circuits. The composite oxide glass-ceramic is SiO 2 -B 2 o 3 -Cs 2 O‑P 2 o 5 -MnO 2 ‑Co 2 o 3 -Ta 2 o 5 -CeO 2 -Er 2 o 3 Composite oxide glass-ceramics; the insulating dielectric slurry includes an organic carrier and an inorganic main phase composed of composite oxide glass-ceramics, and its preparation method is: mixing raw materials according to the proportion, and heating the mixture to 1100-1700°C , keep warm for 1‑24h, then water quenched, dried, ball milled, mixed with an organic carrier in proportion, and finally rolled repeatedly with a three-roll mill to obtain a thick film circuit insulation dielectric slurry, which is used for the large size of stainless steel substrates Power thick film circuit insulation dielectric layer has excellent properties such as large expansion coefficient, good adhesion, high insulation and resistance, high breakdown voltage and low leakage current.

Description

technical field [0001] The invention relates to a composite oxide glass-ceramic, an insulating dielectric paste, a preparation method and application thereof, and belongs to the technical field of thick-film circuits. Background technique [0002] Thick-film electronic paste is the main material for preparing thick-film circuits. It is widely used in electronic packaging, interconnection and passive components. With the increase of the power of thick-film circuits, this technology is gradually applied to electric heating elements, especially in high-end Small household appliances such as rice cookers, electric kettles, electric water heaters, electric irons, disinfection cabinets and hairdressing devices, etc. [0003] Thick-film electronic paste is mainly divided into insulating dielectric paste, resistance paste and conductive paste. The insulating dielectric paste is coated on the surface of the substrate to provide an insulating layer. Its basic composition is a glass ph...
