The silver powder products developed by Shaanxi Coal Industry and Chemical Technology Research Institute have the characteristics of good dispersibility, high tap density, and high product activity. They are suitable for the preparation of solar (or PERC) battery front electrode silver paste, such as battery stacking double printing, step-by-step Printing and multi-bus grid technology, etc., have a wide sintering process window, which is suitable for the preparation of low-temperature sintering pastes for high square resistance PERC batteries. In addition, it can also be used for high-performance shielding paste (high-temperature sintering type), high-conductivity thick film circuit paste (high-temperature sintering type), etc. At present, the silver powder production process management has passed the national quality management system certification (GB/T 19001-2016/ISO 9001:2015) and continues to supply many customers.
