· TaKN3

TaKN3 is a tantalum-based ceramic compound combining tantalum, potassium, nitrogen, and a third element in a ternary or higher-order nitride structure. This material represents an emerging research composition in the family of refractory nitride ceramics, which are valued for extreme hardness, thermal stability, and chemical resistance at high temperatures. Applications of tantalum nitrides and related ternary nitride ceramics are primarily driven by demands in cutting tools, wear-resistant coatings, and high-temperature structural applications where conventional carbides or single-phase nitrides reach performance limits.

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.
