Applications
- In the pharmaceutical industry, superfine calcium carbonate is used as an excipient in tablet formulations. It is added to tablets to improve their compressibility, flowability, and dissolution properties. The high purity of calcium carbonate ensures that it meets the strict quality standards required for pharmaceutical applications.
Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies.[2] The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength.[3] Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.[1]
Lithopone, C.I. Pigment White 5, is a mixture of inorganic compounds, widely used as a white pigment powder. It is composed of a mixture of barium sulfate and zinc sulfide. These insoluble compounds blend well with organic compounds and confer opacity. It was made popular by the cheap production costs, greater coverage. Related white pigments include titanium dioxide, zinc oxide (zinc white), zinc sulfide, and white lead.
- Furthermore, DEF Enterprises, with their state-of-the-art manufacturing facilities, have carved a niche in the market by offering premium-grade B101 Anatase TiO2 powder. Their focus on research and development has led to the creation of specialized formulations that enhance the photocatalytic properties of the material, contributing significantly to the advancement of green technologies.
