What Is Barytes and Where Do I Use It? Barytes (or barite) is the naturally occurring mineral barium sulphate (BaSO4). It is mainly used (70%) as a weighting agent in drilling fluids by the oil and gas industry where baryte’s high specific gravity assists in containing pressures and preventing blowouts. Barytes and barium compounds are also used as fillers […]

Fluorspar

Flurospar

What is Fluorspar and Where Do I Use It? Fluorspar is the commercial name for the naturally occurring mineral fluorite, composed of calcium and fluorine (CaF2). Fluorspar is the predominant commercial source for the chemical element fluorine. Fluorine is a non-metallic element and the lightest of the halogens and therefore largely irreplaceable in its use. […]

Silicon Metal

Silicon

What Is Silicon And Where Do I Use It? Silicon metal (symbol Si), in its pure form, is a grey metallically lustrous metalloid element. Metallurgical grade silicon is known as silicon metal because of its lustrous appearance. Silicon is used mainly in the manufacture of silanes and silicones, as a “hardener” or alloying element to […]

Niobium

Niobium

What is Niobium and Where Do I Use It? Niobium (Nb), formerly known as Columbium (Cb), is a soft, silvery transition metal. It has chemical properties very similar to Tantalum (Ta) making it difficult to distinguish the two and it was only confirmed as a separate element by Charles Hatchett in 1801. It is most […]

Natural Graphite

Graphite

What Is Graphite And Where Do I Use It? Graphite (chemical symbol C) is one of the purest and most crystalline forms of carbon and can be either mined of synthetically made. Natural graphite powders are mined and occur in 3 different forms: vein, amorphous (actually microcrystalline) and flake. Synthetic graphite powders are made from […]
