H2O
ceramic· H2O
H₂O (water) in ceramic form refers to ice or hydrated ceramic materials where water molecules are chemically bound or physically incorporated into a crystalline ceramic structure. This classification is unusual in conventional materials engineering, as pure water is typically considered a liquid or, when frozen, an engineering fluid rather than a structural ceramic; however, water-containing ceramics and ice composites represent an emerging research area with potential applications in cryogenic engineering and specialized structural contexts.

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.
