Features

  •   Anhydrous calcium hydrogen phosphate can be used as an excipient or as a calcium supplement. Due to its good compressibility and fluidity of coarse particles, it can also be used in pharmaceutical preparations. Coarse particles have excellent compressibility and fluidity and can be used for direct pressing. The finer particles can be used in classical wet or rolled granules. Easy transformation from laboratory to industrial production applications.
  •   The main deformation mechanism of coarse granular anhydrous calcium hydrogen phosphate is brittle fracture, which reduces its strain sensitivity and makes it easier to transform from laboratory to industrial production.
  •   The excellent adsorbability can powderize oily substances and extracts. It can be used as a filler and binder for Chinese medicine tablets to adsorb more volatile oils and extractum.
  •   Calcium phosphate and tetracycline have incompatibility, crushed anhydrous calcium hydrogen phosphate surface is alkaline, so it cannot be used with those drugs that are sensitive to alkaline pH.
  •   The results show that the surface acidity and alkalinity of crushed and uncrushed anhydrous calcium hydrogen phosphate are different. The surface of the uncrushed particles is acidic. This is very meaningful to improve the stability of the drug, especially when the pressure tablet process is used, for example, from the rolling process to the direct powder tablet, it is appropriate to change its particle size.
