· Ca4 Al8 O16

Ca₄Al₈O₁₆ is a calcium aluminate ceramic compound belonging to the family of aluminate phases commonly found in portland cement and refractory materials. This material is primarily encountered as a constituent phase rather than a monolithic engineered ceramic, where it contributes to hydration behavior, mechanical strength development, and high-temperature stability in cementitious systems and refractory applications. Engineers select calcium aluminate-based compositions for environments requiring rapid strength gain, chemical resistance to sulfate attack, or thermal performance beyond ordinary portland cement, making it relevant in specialized construction, industrial kilns, and chemical-resistant concrete systems.

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.
