Product Overview
Cadmium Oxide Powder ACS Reagent (CdO) is a brown crystalline or amorphous powder supplied to ACS Reagent specifications. It is odorless, insoluble in water, and classified under CAS 1306-19-0. This is a Class 6.1 toxic material — Packing Group I — that ships under strict DOT hazmat protocols from our Taylor, TX warehouse.
Buyers of this product work in ceramics, electronics, energy storage, and specialty chemical processing. The ACS Reagent grade satisfies purity requirements for analytical and process-critical work where lower-grade cadmium oxide would introduce unacceptable variability.
Why This Grade
ACS Reagent grade means the material meets or exceeds purity and impurity-limit specifications established by the American Chemical Society for reagent chemicals. For a buyer, that matters in two situations: when trace-metal contaminants would interfere with an analytical result, and when a downstream process — semiconductor fabrication, precision ceramic formulation — demands a tightly characterized feedstock.
If your application is less sensitive to impurity profiles (bulk pigment blending, for example), a technical grade may serve. But for any work where you need lot-to-lot consistency and documented purity, ACS Reagent is the standard call.
Chemical Profile
Cadmium oxide is a binary inorganic compound with the molecular formula CdO and a molecular weight of 128.41 g/mol. It presents as a brown crystalline or amorphous powder, odorless, and essentially insoluble in water at less than 1 mg/mL. The crystalline form carries a density of 8.15 g/cm³; the amorphous form is lighter at 6.95 g/cm³. Vapor pressure is negligible at ambient conditions, meaning airborne exposure under normal handling comes from dust, not vapor. CAS number 1306-19-0.
Industrial Applications
Cadmium oxide fills specific roles across several industries. Each application leverages the compound's thermal stability, semiconducting behavior, or reactivity with other metal oxides.
-
Ceramic Glazes — CdO functions as both a flux and a colorant in ceramic glaze formulations. It lowers the melting point of glaze frits and contributes to the development of specific color ranges when combined with other metal oxides in controlled firing atmospheres.
-
Electronics Manufacturing — In semiconductor and optoelectronic fabrication, cadmium oxide serves as a precursor for thin-film deposition and as a component in transparent conducting oxide layers. The ACS Reagent grade supports the purity demands of these processes.
-
Battery Production — CdO is a feedstock in the manufacture of nickel-cadmium cells, where it provides the cadmium electrode material. Consistent purity matters here to maintain cell performance and cycle life.
-
Catalysis — Cadmium oxide acts as a catalyst or catalyst support in certain organic synthesis and gas-phase reactions, where its surface chemistry promotes specific reaction pathways.
-
Pigments and Coatings — CdO-based pigments are incorporated into specialty paints and coatings where cadmium's color stability under heat and UV exposure is required.
Handling & Storage
This material carries a Danger signal word (per the product's GHS classification). The hazard profile is severe and demands disciplined handling:
- H301 — Toxic if swallowed (per the product's GHS classification)
- H330 — Fatal if inhaled (per the product's GHS classification)
- H341 — Suspected of causing genetic defects (per the product's GHS classification)
- H350 — May cause cancer (per the product's GHS classification)
- H361fd — Suspected of damaging fertility or the unborn child (per the product's GHS classification)
- H372 — Causes damage to organs through prolonged or repeated exposure (per the product's GHS classification)
- H410 — Very toxic to aquatic life with long lasting effects (per the product's GHS classification)
Wear appropriate PPE at all times: at minimum, chemical-resistant gloves, splash-proof safety goggles, and a NIOSH-approved respirator rated for toxic dust. Work in a well-ventilated area or under local exhaust ventilation. Avoid generating airborne dust.
Store in a cool, dry, well-ventilated area in tightly sealed HDPE or glass containers. Keep away from acids and strong oxidizers. Prevent environmental release — cadmium compounds are persistent aquatic toxicants. Label all containers clearly and maintain access to the SDS at the point of use.
Hazmat & Shipping
