General description

Copper powder is a metal based powder that can be produced by electrolytic and non-electrolytic techniques. These processes include spray pyrolysis, chemical reduction in the presence of reducing agents, solvothermal and hydrometallurgical methods, and atomization.[1]

Application

Copper (Cu) based powder can be used for a wide range of industrial applications. Its electrical properties and thermal characteristics make it useful in the development of electronic and electrical devices. It can also be used for self-lubricated bearings, brazing, mechanical plating, and cold soldering.[1]

Carbon monoxide (CO) produced in many large-scale industrial oxidation processes is difficult to separate from nitrogen (N2), and afterward, CO is further oxidized to carbon dioxide. Here, we report a soft nanoporous crystalline material that selectively adsorbs CO with adaptable

Lytic polysaccharide monooxygenases (LPMOs) exhibit a mononuclear copper-containing active site and use dioxygen and a reducing agent to oxidatively cleave glycosidic linkages in polysaccharides. LPMOs represent a unique paradigm in carbohydrate turnover and exhibit synergy with hydrolytic enzymes in biomass

Questions

  1. 안녕하세요. 326453 Copper powder (spheroidal), 10-25 μm, 98% 제품에 산화방지 처리가 되어있는지 확인부탁드립니다. 개봉 이후 산화없이 사용 기간이 어느 정도 되는지 또한 확인부탁드립니다. 감사합니다

    1. This material is not chemically treated to protect against oxidation. However, the product is packaged under Nitrogen gas to prevent oxidation. Purging the bottle with Nitrogen gas is recommended after opening. Unfortunately, long term stability has not been determined, but is impacted by conditions and handling.
