01 Feedstock
Ore, monomer, fibre, mineral or scrap that can legally become Cerâmica técnica.
Making Cerâmica técnica is a chain: feedstock, conversion (20th c. spark plugs / WWII carbides), forming, heat, finish, install.
Skip a step and the properties chapter is describing a different object.
Passos de processo
02 Conversion
20th c. spark plugs / WWII carbides
03 Forming
Cast, spin, weave, sinter, foam, laminate or coat — the step that sets anisotropy.
04 Heat / cure
Temper, vulcanise, calcine or dry: skip it and the datasheet is fiction.
05 Finish
Coatings, sizings, facers, galvanizing, anodising, painting.
06 Install
Fasteners, adhesives, DFT, compression, dryness — site quality is a material property.
Rotas
Primary
Virgin route around Germany / US / Japan.
Recycled / secondary
Recycling exists but quality or energy often disappoints.
Specialty
High-spec grades leave the commodity mill.
Site-applied
Coatings, sprays, casts — the factory is sometimes a jobsite.

Limites duros
Envelope
Melting/softening often >2000 °C; conductivity Al2O3 ~20–30; AlN higher; ZrO2 low.
Environment
Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills Cerâmica técnica.
Code
Fire class A1 is a starting letter, not a wall rating.
Process energy and scrap quality belong in the carbon passport, not in a footnote.
