Ammonium Tungstate comes in two main forms – paratungstate and metatungstate. Ammonium paratungstate is a white crystalline salt of ammonium and tungsten, partly soluble in water, and is usually found in one of two states within its chemical compound – either pentahydrate (with five molecules of water) and decahydrate (with ten molecules of water).

WHAT IS AMMONIUM PHOSPHATE?
Ammonium phosphate is the salt of ammonia and phosphoric acid. With a chemical formula of (NH4)3PO4, ammonium phosphate is found in crystalline powder form, and is soluble in water.
WHAT IS ZINC PHOSPHATE?
Zinc phosphate, dihydrate is a white powder with a density of 3.998 (15 degrees Celsius) and a melting point of 900 degrees Celsius. The compound is soluble in acids and ammonium hydroxide; insoluble in water. Zinc phosphate, dihydrate can be used for dental cements; phosphors; and conversion coating of steel, aluminum, and other metal surfaces.
WHAT IS ALUMINUM SULFATE?
Aluminum sulfate is an aluminum salt that is odorless, white or off-white crystalline solid or powder. It is created by the addition of aluminum hydroxide to sulfuric acid and is also known as “alum.” Naturally, it is hydroscopic, and can absorb and hold water molecules.
Aluminum fluoride is white crystals that sublimes (760 mm) at approximately 1272 degrees Celsius. It has a density of 2.882 and is a strong irritant to tissue. Aluminum fluoride, Trihydrate is slightly soluble in water; insoluble in most organic solvents, while Aluminum fluoride, Anhydrous is water insoluble.
Tin (II) chloride, dihydrate, not to be confused with Tin (II) chloride, anhydrous, is created through dissolving tin in hydrochloric acid. This is followed by evaporation and crystallization. Tin (II) chloride, dihydrate, then, is colorless and crystal-like in appearance, and it attracts oxygen from the air. It is also transformed to insoluble oxychloride, which is a two part composite—oxygen and chlorine—with a contributing element or basic chloride. Other terms for Tin (II) chloride, dihydrate include stannous chloride.
Tin (II) fluoride is a slightly water soluble, white, lustrous crystalline powder. Also known as Stannous fluoride, it is widely used as an oral care component in toothpastes, powders, gels and oral rinses. It is known to make teeth more resistant to the acids and bacteria that cause tooth decay. Tin (II) fluoride is the only fluoride that not only works to fight cavity progression and development but also plaque, gingivitis and dental sensitivity.
There are two main forms of Sodium Molybdate. Sodium Molybdate, Dihydrate is a crystalline powder. It loses its water of crystallization at 100 degrees Celsius. It is known to be less toxic than the other corresponding compounds of group 6B elements in the periodic table. Sodium Molybdate, Dihydrate is used in the manufacturing of inorganic and organic pigments, as a corrosion inhibitor, as a bath additive for finishing metals finishing, as a reagent for alkaloids, and as an essential micronutrient for plants and animals.

Sodium Metavanadate is a colorless, monoclinic, prismatic crystals or a pale green crystalline powder. It is soluble in water and noncombustible. Sodium metavanadate is toxic by ingestion; can be used for ink, fur dyeing, photography, inoculation of plant life, mordants and fixers, and corrosive inhibitor in gas scrubbing systems.

Thallium is a bluish-white hued metal found in trace amounts throughout the Earth’s crust. In its purest state thallium is both tasteless and odorless, and was once sourced from smelting other metals. Presently our sources of thallium rely on naturally occurring deposits. Thallium uses today commonly include the production of electronic devices, fiber optics, camera lenses, switches, and closures. Thallium metal is used most notably by the semiconductor, fiber optic, and the glass lens industries. Unfortunately, exposure to thallium metal is harmful to those working closely with the metal. When thallium enters the atmosphere, traces of the substance remain after its use in coal-burning and smelting. Thallium metals are detected in the air, water, and soil long after exposure.
