· SiTaON2

SiTaON₂ is a silicon-tantalum oxynitride ceramic compound that combines the refractory properties of tantalum with the thermal and chemical stability of silicon nitride. This material is primarily investigated for high-temperature structural applications where thermal shock resistance and oxidation resistance are critical, particularly in aerospace and power generation sectors where conventional ceramics face performance limits. SiTaON₂ represents an emerging materials research direction aimed at developing composites that outperform traditional silicon nitride or tantalum oxide in extreme environments.

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.
