What is Aluminium Fluoride?

Posted by Diane Milner on Jan 14, 2019 10:43:00 AM


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.

What You Need to Know About Tin (II) Chloride

Posted by Diane Milner on Dec 3, 2018 12:57:00 PM


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 and a Generation of Healthier Teeth

Posted by Diane Milner on Nov 26, 2018 9:12:00 AM

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.

Why the Agriculture Industry Uses Sodium Molybdate

Posted by Diane Milner on Sep 24, 2018 9:33:00 AM


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.

Three Diseases For Which Sodium Metavanadate Is Used For Treatment

Posted by Diane Milner on Sep 17, 2018 9:18:00 AM


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.

Everyday Uses of Thallium You Didn’t Know About

Posted by Diane Milner on Sep 17, 2018 9:03:00 AM

What Is Thallium Metal?

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.

Surprising Modern Uses of Sublimed Sulfur

Posted by Diane Milner on Sep 10, 2018 9:09:00 AM

What Is Sublimed Sulfur?

Sulfur is a naturally occurring mineral produced by volcanoes; its presence attributed to rife deposits of sulfur throughout the Earth’s crust and upper mantle. Commonly referred to as brimstone, sulfur is found in its raw state surrounding volcanic vents. The mineral is relatively light and reacts with all elements save for gold, platinum, iridium, tellurium, and the noble gases. Interestingly, sulfur produces the following compound sulfide minerals: pyrite, cinnabar, galena, sphalerite, and stibnite. Sulfates produced include gypsum, alunite, and barite.

4 Helpful Calcium Carbonate Uses You Forgot About

Posted by Diane Milner on Aug 27, 2018 8:26:51 AM
What Is Calcium Carbonate (CaCO3)?

Calcium carbonate is naturally found in rock and mineral formations. (Four percent of the Earth’s crust is comprised of the substance.) Calcium carbonate is slightly water soluble, and is thereby leached into natural water systems, resulting in “hard” water. Limestone and chalk are comprised of calcium carbonate– as are coral reefs. The mineral is typically procured via mining and quarrying. Calcium carbonate exists as limestone, chalk, and dolomite, and typically includes impurities like clay.

4 Smart Skincare Uses of Zinc Oxide

Posted by Diane Milner on Aug 20, 2018 9:02:00 AM

What is Zinc Oxide (ZnO)?


Zinc oxide is widely used throughout the skincare industry. In fact, recent developments within sunscreen production have found a new way to incorporate zinc oxide to eliminate the white residue left behind after application. Zinc oxide is derived from zinc, which is an elemental metal. Zinc is unique, as it can carry an electrical charge which communicates differently within the body’s internal organs. Most notably, the immune system, digestive tract, brain, and skin.


Zinc oxide is manmade and is produced by chemically heating zinc alongside oxygen molecules. Both elements are vaporized, condensed, and transformed into a fine white powder.

Top 3 Surprisingly Versatile Uses of Sodium Hydroxide

Posted by Diane Milner on Aug 13, 2018 9:03:00 AM


What Is Sodium Hydroxide?


Sodium Hydroxide (NaOH) is white and odorless solid. It is a common ingredient in cleaning supplies, and perhaps most notably appears in drain and oven cleaning chemicals. Sodium hydroxide causes skin to burn upon contact and will cause irrevocable damage if ingested. (See our safety sheet on Sodium Hydroxide.) However, sodium hydroxide is FDA approved and is “generally recognized as safe” (GRAS). Used across a multitude of industries, some applications of sodium hydroxide include textiles, soap and cleaning products, paper, aluminum processing, petroleum, and bleach production.
