Market Overview

The caustic calcined magnesite market is the industry emphasizing the production, trade, and application of reactive magnesium oxide, also known as caustic magnesia or CCM, derived from calcining magnesite at relatively low temperatures. Caustic calcined magnesite is a highly reactive form of magnesium oxide produced by calcining or burning magnesite at relatively low temperatures.

Due to its superior chemical properties, including high reactivity and purity, caustic calcined magnesite is suitable for use in pharmaceutical, food, and chemical industries. Further, there is growing demand for caustic calcined magnesium in the animal feed sector owing to the awareness about the benefits of magnesium supplementation, with government regulatory support for the use of mineral-rich feed additives. Technological development in the removal and purification process has enabled the production of high purity grade caustic magnesite, which is propelling the market growth. The trend towards magnesium-rich feed in the livestock industry is for better efficiency and effectiveness, which includes improved animal performance, improved reproductive health, and resistance to stress and disease. The growing emphasis on sustainable agricultural practices and technological advancement in production processes, along with ongoing industrialization and infrastructural development, are escalating the market growth opportunities for caustic calcined magnesite.
