Magnesite

 

Magnesite is an anhydrous salt and is the most common form of magnesium carbonate (MgCO3), while Magnesium oxide (MgO) is obtained from magnesite
thanks to a calcination process.

 

C.B.C. Group buys and sells magnesite exclusively for ceramic use.

 

Magnesite occurs in nature in the form of a white mineral and has multiple applications.

Magnesite and its applications

 

In the ceramic industry, magnesite is used in the following applications:

 

  • Glazes: magnesite is added in small percentage to glazes compounds to obtain an opacifying and velvety effect to the touch
  • Ceramic bodies and serigraphies: used as a fluxing agent, magnesite in its purest composition, is perfect for this application
  • Save roller engobes: these compounds contain a high percentage of magnesite, protecting the rollers from deposits of glazes or of the tile itself and reducing the number of interruptions in the production plant, due to cleaning or replacement of damaged rollers.

In agriculture sector, micronized magnesite is used to improve the quality of the soil, used as a nutritional supplement in fertilizers, thanks to its ability to stimulate chlorophyll activity and photosynthesis. While, in zootechnics sector, granular magnesite is added to the feed, in order to achieve the correct amount of magnesium required by the animal diet.

 

In the sports, granular magnesite is used as an antiperspirant to keep hands dry from sweat and increase grip on tools, reducing slipperiness.

Magnesite, thanks to its detoxifying and relaxing properties, is commonly used in the pharmaceutical sector as an anti-acid to neutralize the discomfort caused by heartburn.
In cosmetics, however, for the production of toothpaste and face masks it is excellent for its delicate astringent properties, which help smooth the skin.

 

In plastic, rubber and paint sector it is used as a filler, reinforcing agents and a reducer of production fumes thanks to its neutralizing characteristics.

 

Finally, in the food sector, granular magnesite is mostly used in powder as a food additive with code E504 for its hygroscopic properties that allow to avoid the agglomeration of table salt.
