3.Product Feature And Application
Red Cuprous Oxide (Cu2O) is a red crystalline p-type semiconductor with a 2.0-2.2 eV bandgap, insoluble in water but soluble in dilute acids. It’s used in low-cost solar cells, visible-light detectors, flexible TFTs, and ship antifouling paints, leveraging its photoelectric properties and low cost.
4.Product Details
Red cuprous oxide (Cu2O), an inorganic compound with a distinctive red color, is primarily valued for its use as an effective antifouling agent in marine paints, a agricultural fungicide, and a pigment, while also being a subject of research in semiconductor and solar cell applications.
5.Product Qualification
We have received numerous government awards in China for our outstanding products and integrity in business operations. For exports, we hold REACH certification for multiple products, meeting EU import requirements for copper salt products. We are certified under the ISO 9001 Quality Management System and comply with RoHS standards. We can provide Safety Data Sheets (SDS) and all necessary documentation for every product.
6.Deliver,Shipping And Serving
In terms of packaging, we currently have two packaging options: bags and drums, their standard is 25kg. each pallet can load a total of 1 ton of goods. Some of the products will be in the ordinary bag on the basis of increasing the ton bag for uniform packaging, in the protection of the product at the same time to ensure the beauty of the goods. For some special products or special needs of customers, we can ensure the sealing and safety of the products by the form of barrel.
7.FAQ
