ceramic· JVASP-57182· Ca4Al6O13
Ca₄Al₆O₁₃ is a calcium aluminate ceramic compound, a phase that naturally occurs in Portland cement and refractory materials. It is primarily encountered as a constituent in cement-based systems and high-temperature refractory products rather than as a standalone engineering material, where it contributes to early strength development and thermal stability. This material is notable in the cement and refractory industries because its hydration behavior and phase stability directly influence concrete durability, especially in chemically aggressive or high-temperature environments where conventional Portland cement phases may degrade.

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.
