Cadmium Oxide Powder ACS Reagent

Product Overview

Cadmium Oxide Powder ACS Reagent is a high-purity inorganic oxide with the chemical formula CdO, manufactured to meet strict American Chemical Society (ACS) specifications. This material serves as a critical precursor in industrial applications requiring precise trace metal control, including ceramics, electronics fabrication, and energy storage systems.

With an assay range of 99.0–100.5 wt% (typical 99.7%), this ACS Grade Cadmium Oxide ensures reproducible results in high-temperature processes. It is engineered for low residue and consistent particle characteristics, making it suitable for semiconductor materials and cadmium-based battery components. The product is packaged to minimize moisture uptake and oxidation, ensuring stability across storage and processing.
