Appearance:White Powder
Density:2.3 g/cm3
Melting Point:°Cd ec.)
Refractive Index:1.3991
Water Solubility:Solubility in water, g/100ml at 20°C: 0.18 (poor)
Toxicity:Oral-Rat LD50: 156 mg/kg; Oral-Mouse LD50: 70 mg/kg
Flammability characteristics:Non-combustible; emits toxic fluoride in fire; potassium oxide, silicon oxide fumes; reacts with acid to emit toxic hydrogen fluoride gas
Air and Water Reactions:Slightly soluble in water.
Reactive Group:Salts, Basic
Reactivity Profile:Solutions of potassium fluorosilicate may contain some hydrofluoric acid, which can cause severe chemical burns and is one of the few materials that can etch glass. Unlike other halide ions, fluoride is quite reactive, acting as a weak base and participating in some unique reactions. In particular, fluorides react strongly with compounds containing calcium, magnesium, or silicon ions, which means that solutions containing soluble fluorides are corrosive to both living tissue and glass.
