· JVASP-101783· H4C2O

H4C2O is a lightweight ceramic compound with a very low density, belonging to the family of carbon-oxygen ceramics. This material appears to be a research-phase compound rather than an established commercial ceramic; its potential lies in applications requiring minimal weight combined with ceramic properties such as thermal stability or wear resistance. Engineers considering this material should evaluate whether its specific property combination—particularly its exceptional lightness—addresses a critical constraint in their design that conventional ceramics cannot meet.

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.
