Fluorides are the salts of hydrofluoric acid (HF), which is also known as a hydrofluoric acid. They included in their ionic lattice lattice units as negative ( anions ) fluoride ions (F -). Next be covalent, non-ionic compounds of non-metals , and organic fluorine compounds such as fluorocarbons or carboxylic acid derivatives as outdated denotes fluorides.
Fluorides come in the form of many minerals found in nature. Complex fluorides contain another element within a complex anion, such as boron, aluminum or silicon, and then form eg hexafluorosilicates or tetrafluoroborates.
