gold powder

Gold powder is a powder material composed of high-purity gold particles, with particle size typically controlled in the micrometer to nanometer range. Among them, nano gold powder has a particle size of less than 100 nanometers and has extremely high specific surface area and surface energy. This unique microstructure endows gold powder with excellent conductivity, thermal conductivity, and chemical inertness, making it of significant application value in fields such as electronic manufacturing, catalysis, and biomedical research.

In principle, the conductivity of gold powder originates from the inherent high conductivity of metallic gold, where electrons can freely transfer between particles to form a conductive path. The surface activity of nanoscale gold powder enables sintering and interconnection between particles at lower temperatures, forming a continuous and dense conductive network. The chemical inertness of gold enables gold powder to maintain stable physical and chemical properties in high temperature, high humidity, and corrosive environments, without oxidation or sulfurization.

The core advantages of this product are: excellent electrical and thermal conductivity, and excellent chemical stability; The particle size and morphology can be customized according to application requirements; Suitable for fields such as high-end electronic pastes, catalysis, and biosensing that have strict requirements for material purity and reliability.
