Chemical reactions are all around us, impacting almost every aspect of our lives, often in ways we don’t even realize. But sometimes these reactions require additional “assistance” to improve efficiency and reduce the amount of energy required to achieve completion. And this assistance is provided by chemical catalysts, substances that are added to the chemicals being used to achieve the necessary increased efficiency or decreased energy requirements.

WHAT IS SELENIUM DIOXIDE?
Selenium Dioxide is a crystal or crystalline powder, usually found in either white or cream color. It is toxic in both inhaled or ingested situations and has a melting point of 340 degrees Celsius.
What Is Tartaric Acid?
Tartaric acid is also referred to as dihydroxy succinic acid. Tartaric acid is a colorless, transparent crystals or white, crystalline powder. The compound is odorless, has an acidic taste, and is stable in the air and has a density of 1.76 with a melting point of 170 degrees Celsius. It is soluble in water, alcohol, and ether. Tartaric acid uses include tanning, effervescent beverage, baking powder, fruit esters, and ceramics.
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.
