What are the main differences between gold paste, platinum paste, copper paste dielectric paste, resistance paste, and conductor paste

1. Conductor paste. The main component of the paste is silver, which serves as a conductor after printing and firing. Of course, there are other categories of materials, such asSilver palladium pasteIt is made by doping silver palladium alloy powder or silver palladium powder in different ratios, which can prevent the migration of silver ions at high temperatures and during soldering,wine of the best quality、Platinum pasteCopper paste, etc.

2. Electronic paste. After sintering, it mainly functions as a resistor and is mainly divided into ruthenium based resistor paste and other material paste. The low square resistance of ruthenium based resistor paste is mainly composed of silver palladium ruthenium precious metal, while the high resistance is doped with ruthenium and glass powder. Other resistor pastes include carbon paste, graphite paste, as well as tungsten paste, tungsten molybdenum paste, etc.

3. Medium slurry. The main component is low-temperature glass powder, which plays a role in protecting the resistance paste and conductor paste, waterproof, moisture-proof, insulation, etc.

Electronic paste, as a new type of material, is far superior to traditional circuit equipment such as resistance wires and electric heating tubes, and has the characteristics of environmental protection and energy saving. Its cost is also close to traditional materials, and it will undoubtedly be the main application direction in the future.

Ruthenium dioxide has a wide range of resistance values and high stabilityresistor pasteAn important raw material for conductive phases. China has been conducting experimental work on the preparation of ruthenium dioxide since the early 1970s. There are currently many preparation methods, and ruthenium dioxide powders prepared using different preparation methods have significant differences in performance and price.
The currently mature processes mainly include direct calcination and hydrothermal synthesis. The advantages of direct calcination are simple equipment, minimal participation in chemical reactions, and simple production process. However, the produced ruthenium dioxide powder has large particle size, significant differences in particle morphology, and small specific surface area. The synthesis of ruthenium dioxide powder by hydrothermal method is more complex and involves more chemical reactions compared to the process. However, the produced ruthenium dioxide powder has the advantages of small particle size, good microstructure consistency, large specific surface area, stable resistance and TCR. There are also many processes for synthesizing ruthenium dioxide powder by hydrothermal method.
