K2 Ca2 Si2 H2 O8
ceramic· K2 Ca2 Si2 H2 O8
K₂Ca₂Si₂H₂O₈ is a hydrated alkaline earth silicate ceramic compound containing potassium, calcium, and silicon with structural water. This material belongs to the family of calcium silicate hydrates and related zeolitic/microporous ceramics, which are of significant interest in cement chemistry, geopolymer development, and inorganic binder systems. Industrial applications center on construction materials, wastewater treatment media, and thermal/acoustic insulation products where the hydrated silicate structure provides low density, porosity, and chemical stability; researchers also investigate such compounds for carbon capture and as precursors to advanced refractory or adsorptive ceramics.

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.
