Problems solved by technology

[0002] Resistance paste, also known as electronic paste, is the basic material for the manufacture of thick film components. It is a paste made of solid powder and organic solvents that are uniformly mixed by three-roll rolling. According to the application, it can be divided into medium paste and resistance paste. Material and conductive paste: according to the type of substrate, it can be divided into ceramic substrate, polymer substrate, glass substrate and metal insulating substrate electronic paste, etc.; according to the sintering temperature, it can be divided into high temperature, medium and low temperature drying electronic paste According to the purpose, it can be divided into general electronic paste (making general thick film circuit) and special electronic paste (stainless steel substrate electronic paste, thermistor paste); according to the price of the conductive phase, it can be divided into precious metal electronic paste materials (silver-palladium, ruthenium and gold paste, etc.) and base metal electronic paste (molybdenum-manganese paste), but the existing resistance paste uses more expensive raw materials, which leads to high preparation costs and reduces its promotion. Speed, for this reason, we propose a glass-ceramic resistance paste preparation method
