· JVASP-56724· Ca5WN4O2

Ca5WN4O2 is a ceramic compound combining calcium, tungsten, nitrogen, and oxygen—a rare earth oxynitride belonging to the broader family of refractory and high-performance ceramics. This material is primarily of research and developmental interest rather than established industrial production, with potential applications in extreme-temperature environments, wear-resistant coatings, and advanced structural ceramics where thermal stability and hardness are critical.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
