Formation of Cadmium Oxide

2Cd + O2 → 2CdO

概述

Cadmium burns in oxygen with a brownish-red tint to form cadmium oxide. This reaction is significant because cadmium and its oxide are highly toxic. Cadmium oxide fumes from welding or smelting operations can cause severe and potentially fatal cadmium poisoning.

工业重要性

氧化镉曾用于镍镉充电电池的负极材料，但因镉的高毒性和环境持久性，已被镍氢电池和锂离子电池逐步替代。镉的化合物仍用于部分颜料（镉黄、镉红）和光电材料，但正面临严格的环境法规限制。
