Many of us would have encountered this Natural Calcium Carbonate Powder for the first time in our school time, where we generally utilize it on blackboard. It has been utilized as a writing instrument for over million years. This powder is mainly a micro crystalline and fine material. As limestone, this carbonate function as biogenic rock as well as is more pressed than chalk. However, as marble, our Natural Calcium Carbonate Powder is a dense-crystalline and metamorphic rock that is formulated when limestone or chalk is recrystallized under elevated pressure and temperature. This powder is mainly utilized for mechanical applications. It is extricated through quarrying or mining procedures.
