  • Model PCC - Precipitated Calcium Carbonate (PCC)

    Model PCC - Precipitated Calcium Carbonate (PCC)

    PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals. The most common arrangement for both precipitated and ground calcium carbonates is...

  • Lime or Quicklime

    Lime or Quicklime

    Lime, sometimes referred to as quicklime, is a term commonly applied to a number of related materials. Pure lime is calcium oxide (CaO) formed by “burning” a form of calcium carbonate such as limestone or marble (CaCO3). Carbon dioxide gas (CO2) is released and leaves lime behind. Dolomite, a calcium magnesium carbonate (CaMg(CO3)2) can also be calcined to form dolomitic lime, which has different reactivity due to the presence of MgO. Lime...

  • Dolomite


    Dolomite was named for the French mineralogist Deodat de Dolomieu. The mineral dolomite is commonly found in deposits of a sedimentary rock called dolostone. There are two types of materials often called dolomite, a true chemically uniform calcium magnesium carbonate with the chemical formula CaMg(CO3)2, and a dolomitic limestone, which is just an irregular mixture of calcium and magnesium...

  • Talc Covers

    Talc Covers

    The term talc covers a wide range of natural rocks and minerals, most of which are magnesium silicates. The pure talc mineral is a hydrous magnesium silicate, Mg3Si3O10(OH)2, which theoretically is 31.7 percent MgO, 63.5 percent SiO2, and 4.8 percent H2O. The crystal structure of pure talc is a brucite sheet (Mg12O12H4) sandwiched between two silica (SiO2) sheets, to form talc layers that are superimposed indefinitely. Each layer is electrically...
