· JVASP-128289· TaSi

TaSi is a tantalum silicide ceramic compound that combines tantalum and silicon to create a refractory material with high-temperature stability and oxidation resistance. It is primarily used in aerospace and semiconductor applications where extreme thermal environments and chemical resistance are critical, such as in thermal protection systems, high-temperature coatings, and specialized electronic components. TaSi is valued for its ability to maintain structural integrity at elevated temperatures where conventional metals would fail, making it an important material for next-generation thermal management and harsh-environment engineering.

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.
