ceramic

· TaSiRh

TaSiRh is a ternary ceramic compound combining tantalum, silicon, and rhodium elements, representing a high-performance ceramic alloy system designed for extreme-environment applications. This material belongs to the family of refractory ceramics and is primarily investigated for aerospace and high-temperature structural applications where conventional ceramics or superalloys reach their performance limits. The combination of tantalum's refractory properties, silicon's ceramic-forming capability, and rhodium's oxidation resistance makes this a research-focused material targeting next-generation thermal protection and engine component 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.
