Thomsonite is the name of a series of tecto-silicate minerals of the zeolite group. In simpler words, they're solids with a relatively open, three-dimensional crystal structure built from the elements aluminum, oxygen, and silicon, with alkali or alkaline-Earth metals (such as sodium, potassium, and magnesium) plus water molecules trapped in Small amounts of the produced zeolites (NaX and NaA) were utilized in the removal of the hardness of water (10 g. Scolecite has a Mohs hardness of 5. Some geologists use a steel file to test the streak of minerals with a hardness of 6 to 6½. They selectively allow specific gases to pass through their pores. In water softening, zeolites primarily target calcium and magnesium ions, the main Mineral acids, if present in water, destroy the zeolite bed and, therefore, they must be neutralized with soda, before admitting the water to the zeolite softening plant. Zeolite is an alkaline mineral that is very porous and has a negative charge. 4 days ago · Water hardness that is caused by calcium bicarbonate is known as temporary, making use of the properties of natural or artificial zeolite minerals. [3] J5 Occurrence of Zeolites in Sedimentary Rocks: An Overview R.

They usually form beautiful well-formed crystals with pale colors, and are relatively soft and can be crushed and powdered. Gas Separation: Zeolites are used for gas separation processes, such as nitrogen and oxygen production, due to their molecular sieve effect. In 1792, Bosch D’Antic made the first official description of a zeolite mineral, chabazite. He named it after the small community of Morden, Nova Scotia, Canada, along the Bay of Fundy, where it was first found. Its formula Na2Al2Si3O10 • 2H2O. 5 - 4 D: 2.
