Causmag® XLM is a highly reactive calcined Cryptocrystalline magnesite, produced under closely controlled conditions and precision milled to a superfine particle size, achieving maximum surface area and high chemical reactivity.
Superfine Reactive Magnesium Oxide
Description
Uses
Causmag® XLM is used to supplement sheep and cattle diets where Magnesium levels may be low. Magnesium has a role in metabolism, formation of bone and teeth as well as maintenance of nervous function. It is widely used in the dairy industry for dosing of dairy cattle and to assist in milk fat production. An aqueous slurry applied daily by drench gun provides a quick, clean, positive and economical method of application. XLM high surface area and superfine particle size assists in the bioavailability of magnesia to the animal. Causmag® XLM is also used in the formulation of mineral feed premixes.
XLM is also used in metal precipitation, water treatment, and industrial applications where a high reactivity and surface area are beneficial.
