Production process Introduction
Source factory, high quality, and low price.
Diatomaceous Earth for Medicinal Purposes is a safe-grade porous material obtained through the refining process of high-purity diatom fossils. It is widely used as a drug carrier, flow aid, and adsorbent.
Advantages
High Purity: Carefully selected mineral sources and multi-stage refining processes result in high SiO₂ content and extremely low heavy metal content.
Strong Adsorption Capacity: 80–90% microporous structure provides a high specific surface area, effectively adsorbing moisture and impurities for drying, purification, and controlled-release processes.
Strong Chemical Inertness: The stable silica structure does not react with drug components, and treatment reduces the risk of microbial contamination.
Non-Irritating: Inorganic material, insoluble in acids and alkalis, with low allergenicity, suitable for various pharmaceutical systems.
Product Technical Data Sheet
Low density, high whiteness, low viscosity, and high purity.
