工程陶瓷 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 工程陶瓷 with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.
Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.

工程陶瓷 (Al2O3, ZrO2, SiC, Si3N4…) is a family of grades whose density 3.2–6 g/cm³ class, heat band often >2000 °C, and fire letter A1.
工程陶瓷 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.
This atlas treats 工程陶瓷 as a system: mill route, coatings, tests and the cavity it sits in.
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.
Origin: 20th c. spark plugs / WWII carbides, Germany / US / Japan. The process chapter follows feedstock → conversion → forming → finish → install.
Uses span buildings to defence / safety. Pairings matter: glass.
Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.
Circularity mark 44/100. Ask which scrap, which certificate, which year.
