2、 Basic concepts of high-voltage resistor paste
High voltage resistor paste is an electrical insulation material that has a certain resistance value under high voltage. It is usually composed of polymer materials, oxides, metal powders, and other components. Polymer materials are mainly used to bond oxides and metal powders. Oxides are used to increase resistance, while metal powders are used to improve conductivity.
High voltage resistor pasteThe resistance value is usually between several thousand ohms and several hundred megaohms, and can be adjusted according to actual needs. Its conductivity is usually between 10 ^ -9 and 10 ^ -12 Ω· m, and it has good insulation performance, high temperature resistance, and corrosion resistance.

High voltage resistor pasteThe high-voltage resistor paste prepared by this method has good purity and uniformity, but the preparation process is relatively complicated.
Hydrothermal method
The hydrothermal method is to mix the precursor of oxide with metal powder, and then prepare high-voltage resistor slurry under hydrothermal conditions. The high-voltage resistor slurry prepared by this method has good crystallinity and morphology control, but requires high temperature and pressure.
Physical mixing method
The physical mixing method is to mix oxides and metal powders in a certain proportion, and then prepare high-voltage resistor slurry through steps such as pressing and sintering. The preparation process of high-voltage resistor slurry prepared by this method is simple, but the particle size distribution is wide, making it difficult to control the uniformity of the slurry.
