Unlike steel frying pans that quickly move heat and may overcook sides, alumina offers a gentler, extra also cooking environment, ideal for fragile dishes such as custards, casseroles, and gratins.
Its reduced thermal growth coefficient (~ 8 × 10 ⁻ / K) contributes to impressive thermal shock resistance, allowing direct transition from fridge freezer to stove (usually as much as 1000 ° F or 540 ° C)without splitting– a feature unmatched by many ceramic or glass options.
2.2 Mechanical Stamina and Long-Term Toughness
Alumina porcelains have high compressive strength (isunmọ 2000 MPa) ati ki o dara julọ solidity (9 lori Mohs asekale, 2nd only to diamond and cubic boron nitride), making them very resistant to scratching, damaging, and wear.
This sturdiness makes sure that baking dishes retain their structural and visual qualities over years of duplicated usage, washing, and thermal cycling.
