    en.wikipedia.org/wiki/Polytetrafluoroethylene

    Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [3] The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally invented the compound in 1938. [4]

    en.wikipedia.org/wiki/Tetrafluoroethylene

    A convenient, safe method for generating TFE is the pyrolysis of the sodium salt of pentafluoropropionic acid: [6]. C 2 F 5 CO 2 Na → C 2 F 4 + CO 2 + NaF. The depolymerization reaction – vacuum pyrolysis of PTFE at 650–700 °C (1,200–1,290 °F) in a quartz vessel – is a traditional laboratory synthesis of TFE.

    en.wikipedia.org/wiki/Non-stick_surface

    Not all non-stick pans use Teflon; other non-stick coatings have become available. For example, a mixture of titanium and ceramic can be sandblasted onto the pan surface, and then fired at 2,000 °C (3,630 °F) to produce a non-stick ceramic coating. [19] Ceramic nonstick pans use a finish of silica (silicon dioxide) to prevent sticking.
