· JVASP-12068· Ho2C

Ho2C is a rare-earth transition metal carbide ceramic composed of holmium and carbon, belonging to the family of refractory carbides used in high-temperature and extreme-environment applications. While Ho2C itself remains primarily a research compound rather than a widely commercialized material, rare-earth carbides are investigated for applications requiring exceptional hardness, thermal stability, and resistance to oxidation at elevated temperatures. This material represents the broader potential of rare-earth carbide systems as candidates for advanced tooling, structural components in extreme thermal environments, and specialized coating applications where conventional ceramics reach their 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.
