Usage Of Calcite

Properties and uses
Calcium carbonate is a standout amongst the most prevalent chemicals. Despite the fact that they are accessible in different structures they are chemically similar and just vary physically. They are also called calcite.
Calcium carbonate is a chemical compound with the equation CaCO3.
Calcium carbonate is a white insoluble powder-like substance which is found in minerals, chalk, marble, limestone, calcite, shells, pearl, and so forth. Medicinally, it is utilized as a stomach settling agent or as a calcium supplement, pharmaceutical filler in tablets, and hemodialysis treatment. It is additionally utilized as fillers in cosmetics. It is added to swimming pools as a disinfectant agent and as pH corrector.
Calcium carbonate finds broad utilization in the manufacturing industry as a building material
On the huge scale, it is obtained by passing carbon dioxide gas through calcium hydroxide. In any case, if carbon dioxide is passed in overabundance, it frames the soluble calcium hydrogen-carbonate.
At 1200K, calcium carbonate decomposes to give carbon dioxide and calcium oxide. On reacting with dilute acids, calcium carbonate gives carbon dioxide.
CaCO3 is gotten by utilizing carbon dioxide and slaked lime as raw materials. At the point when carbon dioxide is gone through slaked lime, calcite is acquired. Another strategy to get calcite is by adding sodium carbonate to calcium chloride.
                  

Calcium carbonate is a fleecy powder.
Calcium carbonate has low solubility in water.
Calcium carbonate decomposes to give carbon dioxide when warmed up to 1200K.
When Calcium carbonate reacts with a dilute acid, it frees carbon dioxide as a side-effect.
Calcium carbonate assumes an essential part in construction; cements, and sealants
Calcium carbonate is utilized as a part of various medicinal drugs
Calcium carbonate is utilized as calcium supplements.
Calcium carbonate is utilized in paints, paper, plastics, and so forth.
Calcium carbonate has a density of 2.71 g/mL and melting point of 1,339 °C, as its calcite form.
The primary uses of calcium carbonate are in building materials, earthenware tiles, iron ore purification, paints. It is additionally utilized in toothpastes. Calcium carbonate isn't dangerous and is safe for utilization. But excess calcium in the body can prompt hypercalcemia or milk-alkali syndrome, which incorporates side effects like stomach pain and heaving, and can be lethal in some cases.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread th...

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product. Figure: Single Walled Carbon Nanotube (SWCNT) It ha...
