Ca3SiO5
ceramic· Ca3SiO5
Ca₃SiO₅ (tricalcium silicate) is the primary mineral phase in Portland cement clinker, one of the most widely produced industrial ceramics worldwide. This calcium silicate compound hydrates when mixed with water to form calcium silicate hydrate gels, which provide the binding strength in concrete and mortar. It is chosen over alternative binders because of its excellent long-term strength development, cost-effectiveness, and proven performance in infrastructure applications spanning over a century.

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.
