· Ta4N5

Ta₄N₅ is a tantalum nitride ceramic compound that belongs to the refractory metal nitride family. It combines tantalum's high melting point and chemical inertness with nitrogen to create a hard, dense material suitable for extreme environments. This material is primarily of research and specialized industrial interest, valued in applications requiring exceptional hardness, corrosion resistance, and thermal stability at elevated temperatures.

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.
