Synthesis and Characterisation of Calcium Carbonate ...

Limestone has been identified as one of the raw material with the highest content of calcium carbonate. According to the Ministry of Natural Resources and Environmental of Malaysia, from 2007 until 2010 the numbers of limestone production recorded are more than 32,000 metric tons each year. With the given statistic, the extensive limestone

Abstract. In this study, the CaCO3 powder has been successfully synthesized by mixing CaCl2 from natural limestone and Na2CO3 in the same molar ratio. The mixing process of solutions was carried out by employing the molar contents of 0.125, 0.25, 0.375 and 0.5M at varying temperatures of 30, 40, 60 and 80ᴼC. The produced CaCO3 microparticles were characterized by scanning electron microscopy ...

Natural dolomitic limestone (NDL) is employed as a heterogeneous green catalyst for the synthesis of medicinally valuable benzimidazoles, dihydropyrimidinones, and highly functionalized pyridines via C–N, C–C, and C–S bond formations in a mixture of ethanol and H 2 O under ultrasound irradiation. The catalyst is characterized by XRD, FTIR, Raman spectroscopy, SEM, and EDAX analysis.

The synthesis of pure calcium carbonate nanocrystals using a high pressure homogeniser (HPH) via a microemulsion system produced uniform nanosized particles, which were characterised using transmission electron microscopy (TEM), field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA).

limestone | Characteristics, Uses, & Facts | Britannica

Limestone is a type of a sedimentary rock that is found naturally in the earth's environment. The rock comprises primarily of chemical compound calcium carbonate (CaCO 3) in the form of calcite which is yet again a type of a mineral.It also contains other materials like quartz, clay minerals, pyrite, feldspar, and siderite amongst others.
