The evolution of the size distribution and of the specific surface area of the particles versus grinding time was measured revealing that an agglomeration phenomenon takes place during the comminution process. The X-ray diffraction profiles …

It uses a simple adapter that makes a directory of CSV files appear to be a schema containing tables. Calcite does the rest, and provides a full SQL interface. Calcite-example-CSV is a fully functional adapter for Calcite that reads text files in CSV ...
view moreCalcite, crystallizing in the rhombohedral crystal system is the thermodynamically stable phase of calcium carbonate. Aragonite, calcite's orthorhombic polymorph, is about 1.5 times more soluble than calcite. Magnesian calcite is an important sub-group of carbonates that occurs as skeletal components and marine cements.
