· HfP

Hafnium phosphide (HfP) is a refractory ceramic compound combining hafnium and phosphorus, belonging to the family of transition metal phosphides. This material is primarily of research and emerging-application interest rather than established high-volume production, valued for its high hardness, thermal stability, and chemical resistance in extreme environments. Potential applications include high-temperature structural components, wear-resistant coatings, and advanced semiconductor or photonic devices where conventional ceramics or metals prove inadequate.

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.
