Paf ( Potassium/Aluminium/Fluoride ) is a solid inorganic fused salt. The product can be supplied as lumps ( 10 x 15 x 15 cm ) or as crushed powder. Handling of solid paf would not normally constitute a toxic hazard. Decomposition of this compound will only take place when molten at high tempreratures. On the contrary paf in fine powder form presents a potential dust hazards. Precautionary measures should be taken to avoid inhalation and indigestion. Paf doesn’t exhibit a stoichiometric chemical composition. It is a mixture of potassium hexa-and tetra- fluoroaluminates with the latter predominant. It appears grey to white crystalline coloured and its melting point is 560-600 °C . Paf should be respected in the same way as other inorganic metal fluorides, like cryolite, as inhibiting toxic properties however these solid compounds are neutral in comparison to the dustinctive hazards of gaseous and liquids fluorine chemicals.
