Calcium carbonate among many other inorganic nanosized particles offers promising results for such applications. We have synthesized calcium carbonate nanoparticles using polymer mediated growth technique, where one of the ions bound within polymer matrix and the other diffuses and reacts to form desired compound. The synthesized nanoparticles ...
Calcium Carbonate Solubility. The solubility of calcite (CaCO 3, Calcite) seems to show an inverse solubility with respect to temperature. This seems contradictory to what is normally observed in the field. The confusion occurs because of the assumed presence of carbon dioxide (CO 2 ). Normally atmospheric air contains approximately 300 ppm CO 2.
In August 1998, the company bought a light calcium carbonate factory at 6 million RMB, then built a light calcium carbonate production line, which annual output is up to 30,000 tons. 1996 In May 1996, the company acquired a 0.9 square kilometers of calcium carbonate mine.
The CaCO 3 micro- and nanoparticles are also capable of acting as delivery vehicles for various hydrophobic and hydrophilic drugs. Because of the slow biodegradation of matrices, these CaCO 3 micro- and nanoparticles can also be used as sustained drug release systems as they can aid in retaining the drug into the system for a longer time.
Calcium Carbonate (CaCO3) is a naturally found material in chalk, limestone, and marble. It is composed of three elements which include carbon, oxygen, and calcium. It is formed by reacting carbon dioxide with slaked or burnt lime. It can be used for a variety of applications ranging from industrial, food to agriculture.
Also, due to the slow degradation of CaCO3 matrices, these nanoparticles can be used as sustained release systems to retain drugs in cancer tissues for longer times after administration. Areas covered: Development of drug delivery carriers using CaCO3 nanoparticles has been reviewed. The current state of CaCO3 nanoparticles as cancer drug ...
