1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...
As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium , iridium and palladium by mass and iridium, gold and platinum by volume . Carbon in the form of diamond can be more expensive than rhodium.

The exact number of cans per pound can't be quantified due to different measurements. Depending on the brand, estimates show there are usually 32 to 35 cans per pound. For smaller, more common 12 ...

From early 2020 HFCs (including R-404A, R-134a and R-410A) are being superseded: Residential air-conditioning systems and heat pumps are increasingly using R-32. This still has a GWP of more than 600. Progressive devices use refrigerants with almost no climate impact, namely R-290 (propane), R-600a (isobutane) or R-1234yf (less flammable, in cars).
