· Ta4AlC3

Ta4AlC3 is a ternary ceramic compound belonging to the MAX phase family, which combines metallic and ceramic characteristics through a layered crystal structure of transition metals, aluminum, and carbon. This material class is notable for exceptional damage tolerance, thermal shock resistance, and machinability—properties rarely combined in traditional ceramics—making it attractive for high-temperature structural applications where conventional monolithic ceramics would fail. While primarily in the research and development phase, Ta4AlC3 represents the expanding MAX phase platform for next-generation aerospace and energy systems requiring materials that maintain strength at elevated temperatures while resisting thermal cycling and mechanical shock.

Export Control

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.
