· Ca4 Al6 O13

Ca₄Al₆O₁₃ is a calcium aluminate ceramic compound belonging to the family of high-temperature aluminate phases commonly found in Portland cement clinker and refractory materials. This material is primarily encountered as a constituent phase in cement-based systems and high-temperature applications where its thermal stability and chemical resistance are advantageous. Engineers select calcium aluminates for applications requiring excellent bonding at elevated temperatures, rapid early strength development, and resistance to chemical attack, making them valuable in specialized refractory formulations, castable ceramics, and advanced binder systems.

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.
