Aragonite PowerPoint PPT Presentations

Oolitic aragonite is the purest form of calcium carbonate precipitated in the oceans naturally. It has its orthorhombic and bipyramidal crystalline structure. For more information visit Website

Aragonite is one of the sand types present worldwide mainly available in Bahamas Region. These aragonite mineral has carbonate ions and one of the well known form of calcium carbonate. There are mainly three forms of calcium carbonate. For more details visit Pisa Carolina

Aragonite is a sand-type material that is available worldwide mainly in the Bahamas Region. This aragonite mineral is mostly made up of carbonate ions. It is a popular form of calcium carbonate. For more details please visit Website

Oolitic aragonite is a unique mineral that appears as same as sand but it has huge difference compared with the normal beach sand. These minerals are formed in the lower layer of the water in the Banks of Bahamas. For more details visit Pisa Carolina

Aragonite is one of the most premier source for the calcium carbonate mineral. This type of mineral is natural forming renewable minerals from the biological and chemical process occurs in the marine or fresh water environments. The calcium carbonate also has other two types of source called calcite and vaterite. But, this only considered as the pure and the premier source of calcium carbonate.

Just like the shell of a mollusk, a pearl is composed of calcium carbonate (mainly aragonite or a mixture of aragonite and calcite) in minute crystalline form, which has deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearls, can occur.

Limestone is a natural stone which is formed from calcite and aragonite. It is a sedimentary rock and due to the impurities present in the form of clay, sand, iron oxide or organic remains, limestone may exhibit different colours. Indian limestone is naturally porous, and it can be easily cut and is not affected much by variations in temperature. @ https://www.elegantgranites.com/limestone-tiles.html

Argonite is a solid material that can reduce oxygen levels and suffocate fires. The material's low oxygen content makes it unsustainable for humans, but it is safe for a short period of time. For this reason, argonite is also often used in emergency response plans. Moreover, it can be used in hospitals, data centers, and other environments. In fact, it is widely used as an alternative to chemical fire suppression.For more details kindly visit https://knowaboutcalciumsalts.tumblr.com/post/693351128321196032/argonite-what-is-it
