· JVASP-112604· Ca2Al3O8

Ca₂Al₃O₈ is a calcium aluminate ceramic compound that forms part of the aluminate family of materials commonly encountered in Portland cement chemistry and refractory applications. This phase appears as a constituent in cement clinker and high-alumina refractory systems, where it contributes to binding behavior and thermal stability at elevated temperatures. Engineers encounter this material primarily as a component phase rather than in pure form, valued for its role in improving early strength development and refractoriness in cement-based and refractory products.

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.
