Overview

Cadmium Oxide Powder (CdO) is a high-purity inorganic compound that appears as a reddish-brown to yellow-brown crystalline powder. With exceptional thermal stability and unique electrical properties, this odorless material serves as a critical component in advanced manufacturing processes across electronics, ceramics, and specialized industrial applications. Its molecular formula CdO represents a dense oxide with remarkable conductivity characteristics that make it indispensable for cutting-edge technology applications.

Key Applications

Semiconductor Manufacturing: Essential precursor material for advanced semiconductor research and development, providing precise electrical properties required for modern electronic components
Electronic Ceramics: Critical ingredient in manufacturing high-performance electronic ceramics used in capacitors, resistors, and specialized electronic devices
Electroplating Operations: Key component in cadmium plating bath formulations for corrosion-resistant coatings on metal substrates
Glass & Ceramic Pigmentation: Provides distinctive coloration and enhanced properties in specialty glass and ceramic manufacturing processes

Safety & Handling

Cadmium oxide requires strict safety protocols due to its toxic nature. Personnel must wear appropriate personal protective equipment including NIOSH-approved respirators, chemical-resistant gloves, and protective clothing. Work areas must maintain adequate ventilation systems to prevent inhalation exposure. This material is non-flammable with no flash point, but requires careful handling to prevent dust formation. Always consult the Safety Data Sheet before use and ensure compliance with OSHA regulations for cadmium exposure limits.

Storage & Shelf Life

Store cadmium oxide powder in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials including strong acids and oxidizing agents. The material should be kept in original packaging when not in use to prevent contamination and moisture absorption. Properly stored material maintains stability indefinitely under recommended conditions. Containers should be clearly labeled and stored in designated hazardous material storage areas with appropriate secondary containment.

Frequently Asked Questions

What is cadmium oxide powder and what is it used for?

Cadmium oxide (CdO) is a red-brown inorganic powder used as a precursor or additive in pigments, electroplating, ceramics, catalysts, battery materials, semiconductor research and various laboratory applications.

How should cadmium oxide powder be stored and what is its shelf life?

Store cadmium oxide in a cool, dry, well-ventilated area in tightly sealed, labeled containers away from acids and reducing agents; it is chemically stable and, if kept dry and sealed, can remain usable for extended periods—suppliers typically state a recommended shelf life on the COA.

What safety precautions and personal protective equipment are required when handling cadmium oxide powder?

Cadmium oxide is toxic and a known carcinogen; use engineering controls (local exhaust/fume hood), wear appropriate PPE (NIOSH/EN‑approved respirator for dust, gloves, eye protection, lab coat) and avoid inhalation, ingestion or skin contact while following the product SDS for emergency measures.

How do different concentrations or purities of cadmium oxide powder affect its performance and hazards?

Purity and additives affect chemical reactivity, electronic properties and application suitability—higher purities (commonly used for electronic/semiconductor work) offer fewer trace contaminants, while lower grades may be acceptable for pigments; regardless of concentration, cadmium oxide retains its toxic hazards and handling precautions.

What documentation is available when purchasing cadmium oxide powder?

Suppliers typically provide a Safety Data Sheet (SDS), Certificate of Analysis (COA), Technical Data Sheet (TDS) and transport documents; regulatory or compliance declarations (REACH, RoHS) can be supplied on request where applicable.

How is cadmium oxide powder packaged and shipped safely?

Cadmium oxide is shipped as a hazardous material under applicable transport regulations and is usually packaged in sealed inner bags within fiber drums, steel drums or plastic pails with appropriate labeling and documentation; carriers require hazardous goods declarations and adherence to local and international rules (IATA/IMDG/ADR).

What materials is cadmium oxide compatible or incompatible with?

Cadmium oxide is generally compatible with glass, stainless steel and some plastics (e.g., HDPE) for storage, but it reacts with strong acids to form soluble cadmium salts and with strong reducing agents to give cadmium metal, so avoid contact with incompatible chemicals and reactive metals.

What are the key technical specifications for cadmium oxide powder I should check before buying?

Key specs include chemical formula (CdO), molecular weight (~128.41 g/mol), appearance (red-brown powder), assay/purity, particle size distribution, specific surface area, impurity limits and packaging form; request the COA for batch-specific data.

Which industries and applications commonly use cadmium oxide powder?

Cadmium oxide is used in pigments and coatings, electroplating, ceramic glazes, catalysts, nickel‑cadmium battery manufacture, semiconductor and optoelectronic research, and various laboratory and industrial processes.

How can I purchase cadmium oxide powder and what availability or regulatory restrictions should I expect?

Cadmium oxide is sold through chemical suppliers in various grades and package sizes with typical lead times; purchasers should expect regulatory controls, documentation requirements and possible restrictions on sale or export—provide company and end‑use information to suppliers to ensure compliant handling and delivery.
