Product description
Product Description
Firstly, just introduce our company in short. Dalian CR Science Development Co.,Ltd is the manufature of Brucite located in Liaoning province.
Our main mineral products are Brucite, Magnesite, Magnesium Oxide, Caustic Calcined Magnesite, Magnesium Hydroxide, Calcined Brucite, Electrical grade magnesium oxide, Fused Magnesia, Dead Burnt Magnesite and so on.
1. Raw Brucite
Brucite is Magnesium Hydroxide in mineral form. It is easily the most cost effective source of Magnesium Hydroxide as a dry material. Brucite can easily be milled down to a sub-10 micron particle size giving it reaction and neutralization times equal to the Magnesite and Magnesium Chloride sources of Mg(OH)2.
Customers utilizing Magnesium Hydroxide from Brucite include:
Public Municipal Waste Water Treatment Facilities
Animal Rendering Facilities
Brewery Waste Water
Ethanol Production Facilities
Ceramics Manufacturers
Struvite Production Facilities
2. Calcined Brucite
Calcined brucite is often used as additive in chemical fertilizer,in environmental protection field, magnesium industry, medical industry,it also used as furnace additive in steel making industry.
