· JVASP-110163· Ta2Ti2NbC5

Ta2Ti2NbC5 is a high-entropy metal carbide composed of tantalum, titanium, niobium, and carbon in a refractory ceramic matrix. This material represents an emerging class of multi-element carbide compounds designed to combine the hardness and thermal stability of traditional refractory carbides with enhanced damage tolerance and processing flexibility from entropy-stabilized phases. While primarily in the research and development stage, Ta2Ti2NbC5 is being investigated as a candidate for extreme-environment applications where conventional tungsten or tantalum carbides reach performance limits, offering potential advantages in thermal shock resistance and high-temperature mechanical retention compared to single-phase alternatives.

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.
