Cadmium Oxide Powder Technical

Product Overview

Cadmium Oxide Powder Technical Grade (Cadmium(II) oxide, CdO) is a high-purity inorganic compound utilized extensively in industrial manufacturing. This yellow to red solid serves as a critical precursor for pigments, a semiconductor material, and a component in specialized ceramic applications. With a typical assay ranging from 99.0% to 100.5%, this material offers excellent thermal stability and specific electrical properties required for electronic components and high-performance coating systems.

Supplied as a free-flowing powder, Technical Grade Cadmium Oxide is insoluble in water but soluble in acids, allowing for controlled integration into chemical processes. It is widely used in the production of cadmium electrodes for storage batteries, ceramic glazes, and as a catalyst in organic reactions. This product is strictly intended for industrial and institutional use by qualified professionals.
