エンジニアリングセラミックス 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 エンジニアリングセラミックス 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.

Deep dive: エンジニアリングセラミックス

エンジニアリングセラミックス (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.

What “the material” actually is

エンジニアリングセラミックス 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 エンジニアリングセラミックス as a system: mill route, coatings, tests and the cavity it sits in.

Heat, fire and insulation

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.

How it is made and used

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.

Market and circularity

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.

よくある質問

Is エンジニアリングセラミックス non-combustible?

Declared reaction class in this atlas: A1. Assemblies still need resistance tests.

Does エンジニアリングセラミックス insulate?

Thermal mark 46/100 versus the atlas. Conductivity note: Al2O3 ~20–30; AlN higher; ZrO2 low.

What is the density band?

3.2–6 g/cm³ class

How is it made?

Origin story: 20th c. spark plugs / WWII carbides (Germany / US / Japan).

Can it be recycled?

Circularity mark 44/100 — editorial, route-specific.

Typical melting or failure heat?

often >2000 °C

What should it be paired with?

glass: Amorphous silicate vs crystalline engineering body.

Where is it specified?

Buildings, transport, energy and consumer goods — see the uses chapter.
