ABX3 (e.g. CH3NH3PbI3)
ChemistryPerovskite (PV) is specified as ABX3 (e.g. CH3NH3PbI3). Density band thin-film.

Quick answers
Is Perovskite (PV) non-combustible?
Declared reaction class in this atlas: device, not a building class. Assemblies still need resistance tests.
Does Perovskite (PV) insulate?
Thermal mark 8/100 versus the atlas. Conductivity note: modest; not an insulator product.
What is the density band?
thin-film
How is it made?
Origin story: Miyasaka 2009 DSSC; 2012 solid-state jump (Japan / Oxford / Korea).
Can it be recycled?
Circularity mark 40/100 — editorial, route-specific.
Typical melting or failure heat?
soft lattices; heat-sensitive
heat 24 · fire 20
What holds Perovskite (PV) together is not the nickname. Formula ABX3 (e.g. CH3NH3PbI3), density thin-film.
Meters are atlas-relative. Grades are the SKUs buyers write.
Phases
Microstructure
OrderProcessing sets grain, crystallinity or fibre orientation — the reason two lots of Perovskite (PV) can test differently.
Interfaces
SurfacesCoatings, oxide films, sizings or paper faces often decide weather and fire behaviour more than the bulk brochure.
Defects
FlawsInclusions, voids, knots, pinholes or residual stress start the failures that mill certificates do not list.
Grades
VariantsPerovskite (PV) is a family. Grade names below are the ones buyers actually write on RFQs.
Ageing
TimeMoisture, UV, creep, hydrogen or carbonation shift properties in service. Design to the aged state.

Strength18
Strength is an editorial 0–100 mark relative to the other 31 materials in this atlas — not a laboratory certificate.
Heat envelope24
Heat envelope is an editorial 0–100 mark relative to the other 31 materials in this atlas — not a laboratory certificate.
Fire behaviour20
Fire behaviour is an editorial 0–100 mark relative to the other 31 materials in this atlas — not a laboratory certificate.
Insulation8
Insulation is an editorial 0–100 mark relative to the other 31 materials in this atlas — not a laboratory certificate.
Workability48
Workability is an editorial 0–100 mark relative to the other 31 materials in this atlas — not a laboratory certificate.
Circularity40
Circularity is an editorial 0–100 mark relative to the other 31 materials in this atlas — not a laboratory certificate.

Bonds
Primary bonding
Perovskite (PV) holds together by ionic/covalent networks.
Secondary forces
Hydrogen bonds, van der Waals stacks or grain-boundary cohesion set toughness and moisture uptake.
Composites & fills
Fillers, fibres, plasticisers or aggregates are part of the real product, not impurities.
Environment film
Oxides, chars, sizings or paints are the layer the world actually meets.
Change the grade, the coating or the moisture and you have a different material with the same English name.
