Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number. Technical ceramics is sold as grades, not as a single substance. Chemistry Al2O3, ZrO2, SiC, Si3N4…, density 3.2–6 g/cm³ class, heat band often >2000 °C.

Technical ceramics · Technical ceramics is one of 32 materials in this atlas, grouped
Technical ceramics is one of 32 materials in this atlas, grouped under ceramics: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue. Scores compare Technical ceramics with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.

Conductivity note: Al2O3 ~20–30; AlN higher; ZrO2 low. Insulation score 46/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: A1. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
