· ZrC

Zirconium carbide (ZrC) is a ceramic compound belonging to the refractory carbide family, characterized by extremely high melting point and hardness. It is used primarily in high-temperature structural applications, cutting tools, and wear-resistant coatings where conventional materials fail due to thermal or mechanical stress. Engineers select ZrC for environments exceeding 3000°C or demanding extreme hardness combined with chemical inertness, such as in aerospace thermal protection, nuclear reactor components, and industrial cutting implements.

Regulatory Screening

Environmental

Export Control

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.
