Why calcium carbonate powder needs coating? Can't it be put into use directly? Some may have such wonders. Of course, calcium carbonate powder can be put into use directly, but powder coating improves its performance greatly. Powder coating aims to coat powder with modifier so as to change the physical or chemical property of powder.

The CaCO3 fibers were converted to nanocrystalline hydroxyapatite (HA) fibers by treatment in a dilute phosphate solution. The resulting hydroxyapatite had a plate-like crystal structure with resemblance to bone mineral. The calcium carbonate and hydroxyapatite fibers are interesting materials for bone scaffolds and bioactive coatings.
