Sylvite, or sylvine, is potassium chloride (KCl) in natural mineral form. It forms crystals in the isometric system very similar to normal rock salt, halite (NaCl). The two are, in fact, isomorphous. Sylvite is colorless to white with shades of yellow and red due to inclusions.

What is the definition of sylvite?

: a mineral that is a natural potassium chloride and occurs in colorless cubes or crystalline masses.

Is sylvite a potash?

Sylvite is the main source of potash, which is an important ingredient in fertilizers.

How can you tell halite and sylvite apart?

Sylvite commonly has octahedral faces truncating the corners of the cubic crystals. So does halite, but this characteristic is much more prevalent in sylvite than in halite. Better tests include a taste test in which halite, salt, will taste salty and sylvite tastes bitter.

What group does sylvite belong to?

5 Halides. The halides group of minerals are salts of sodium, fluoride, and hydrochloric acid. The minerals halite, sylvite, and carnallite from this group contain exclusive chloride having petrogenic significance. Halite (NaCl) is the mineral form of sodium chloride and is commonly known as rock salt.
