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 (Na Cl). The two are, in fact, isomorphous. [5] . Sylvite is colorless to white with shades of yellow and red due to inclusions. It has a Mohs hardness of 2.5 and a specific gravity of 1.99.

Silvi Salt meets both PennDOT and NJDOT standards, which require moisture less than 2%, anti-caking agent at 100ppm, and a sodium chloride purity over 98%. We also blend and make our own NJDOT- and NJ Turnpike-approved treated rock salt.

Sylvite is an economically important mineral and is extensively mined, though it is rarely represented in mineral collections as attractive specimens. It is the most significant form of potash, or potassium-bearing compounds, and has many industrial uses.

sylvite, halide mineral, potassium chloride (KCl), the chief source of potassium. It is rarer than halite (sodium chloride) and occurs as soft, bitter-tasting, white or grayish, glassy cubes or as masses with halite and gypsum in evaporite deposits in the vicinity of Stassfurt, Ger., and in southwestern New Mexico, U.S.

Sylvite (Sylvite). 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.

From Latin "sal digestibus Sylvii", salts of Sylvius, named after Franz (Franciscus) Sylvius de le Boë (15 March 1614, Hanau, Holy Roman Empire - 19 November 1672, Leiden, Republic of the United Netherlands), a physician and chemist of Leiden, Netherlands.

Sylvinite is a sedimentary rock made of a mechanical mixture of the minerals sylvite (KCl, or potassium chloride) and halite (NaCl, or sodium chloride). [1][2] Sylvinite is the most important source for the production of potash in North America, Russia and the UK. [2][3] Most Canadian operations mine sylvinite with proportions of approximately 3...

Named after the Dutch chemist, Sylvia de la Boe (1614-1672). Comments: Translucent sylvite crystal cluster, somewhat deliquescent. Location: F.O. Kailwerk, Sigmundshall, near Wunstorf, Niedersachsen, Germany. Scale: See Photo. Warning: this large pop-up is very compute intensive and may not work well with some computers.

The main chloride minerals found in the above deposits are: halite, silvin, sylvinite and carnalite, and cainite, including magnesium sulfate. Galite is a mineral of chlorides subclass, a crystalline form of sodium chloride (NaCl). Raw materials from which the salt and technical salt is made.

Alternate Names: Potassium chloride, KCL, Silvin, Silvine. Description: Soluble source of K 2 O. This can be used as an alternative to NaCl in the salt glaze process. Materials that source Na2O, K2O, Li2O, CaO, MgO and other fluxes but are not feldspars or frits. Remember that materials can be flux sources but also perform many other roles.
