· JVASP-106189· Cr2OF2

Cr2OF2 is an oxyfluoride ceramic compound containing chromium, oxygen, and fluorine elements. This material represents a specialized ceramic composition that combines oxidic and fluoride chemistry, making it of primary interest in research and advanced materials development rather than established high-volume industrial production. The oxyfluoride ceramic family is explored for applications requiring unique combinations of thermal stability, chemical resistance, and specialized electronic or optical properties that differ from conventional oxide ceramics.

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.
