Caustic Calcined Magnesia

Caustic Calcined Magnesia is the natural grade of Magnesium Oxide. It has been calcined at temperatures ranging from 700 - 1000 ºC of the natural Magnesium Carbonate (MgCO3). Because of the different methods of calcination and nature of the raw magnesite used, CCM exhibits variable functions and properties. I.E.: purity/color/density/reactivity etc. 

Owing to our carefully selected ore, extensive technology experience and advanced facilities, our products are available in a wide range of properties and are used in a wide variety of applications, including: Plant Nutrition, Feed Additives, Pulp & paper, Rubber & Plastic, SMC & BMC, Friction Materia, Soil Remediation, Cementing, Magnesium Oxide Board, etc.

We serve practically all applications where Caustic Calcined Magnesia is used.

Dead Burnt Magnesia

Dead Burnt Magnesia is calcined at temperatures ranging from 1500 - 2000 ºC of the natural Magnesium Carbonate (MgCO3) or CCM. As its name "Dead burnt", DBM exhibits high bulk density and hydration resistance, but low chemical reactivity. It finds its use most popularly in the refractory application, I.E.: refractory bricks, monolithic gunning materials, in the production of tundish etc. It can be classified as Middle-grade DBM and High purity DBM. Besides refractory application, DBM has also been widely applied in: Braking lining and pads, Leather tanning, Welding flux, foundry. 

Fused Magnesia

Fused Magnesia is produced through a sophisticated and tightly controlled manufacturing operation by fusing high grade of raw magnesite finely selected or balls of high purity CCM (Natural or Synthetic grade). The fusing temperature are normally up to 2800 - 3000 ºC; thus, we can get also Large Crystal FM whose MgO content can reach up to 99% with super low impurities. FM exhibits high purity, big crystalline, dense structure, moisture resistance and the electric insulation which makes it a good material for: Magnesia monolithic refractories, Heating Elements, Thermocouple, Foundry, etc.

Brucite

Nature has provided us with endless riches. For centuries, man has explored the depths of the Earth, constantly making new discoveries. That was how a unique natural mineral, called Brucite, was discovered. Among industrial minerals, Brucite ranks first in terms of magnesium content. We have been discovering the potential and versatility of Brucite for the world. Brucite has so many industrial applications, including an effective mineral flame retardant and smoke absorber for polymer compounds, a new-generation reagent for cleaning water and industrial gases from harmful impurities both on- and off-shore, an important source of magnesium in mineral fertilizers, animal feed and premixes, etc.

Synthetic Magnesium Oxide

Unlike natural magnesia produced from ore calcination, synthetic magnesia results from chemical reactions of compounds. After extracting Magnesium Chloride from brine, salt lake or seawater, we firstly use Magnesium Chloride and other substance to produce Magnesium Hydroxide and then heat Magnesium Hydroxide to Magnesium Oxide. The said other substance is usually Calcium Oxide or Calcium Hydroxide, but Ammonia or Sodium Hydroxide can also be used. Synthetic Magnesium Oxide has higher purity, lower impurities, magnesium oxide content usually reaches more than 99%. So in addition to the field of refractory materials, it can also be used in high-purity reagents, special functional materials, electronic components, photoconductive materials, food additives, pharmaceutical additives and other fields. 

Synthetic Magnesium Hydroxide

A very common way, accounting for approximately 50% of the global supply of Magnesium Hydroxide, is precipitating the solution from a combination of brine/salt lake/seawater and Calcium Oxide or Calcium Hydroxide. This method was first undertaken in 19th century France and has since been perfected by the largest global synthetic producers: China, Israel, and the United States. This process, completed in a series of agitating reactors and supplemented with washing and filtration, has very specific temperature, time, and pressure requirements, which ultimately impact the quality of the resulting Magnesium Hydroxide. Because of these variables, the final product requires significant testing to ensure the meeting of quality and purity standards. 

Nano Magnesium

With the rapid development of science and technology, simple inorganic salts such as magnesium oxide, magnesium hydroxide and magnesium carbonate have been made into nanoscale products and have begun to be widely used in segmentation fields with high precision requirements. Reducing such magnesium inorganic salts to the nanoscale can lead to them having unique properties that are not possible in the bulk material at the macroscales.

Mg(OH)2 Slurry/Suspension

In order to better play its properties, in some applications, magnesium hydroxide is necessary to be made into a slurry/suspension which is recognized as magnesia milk. Magnesium hydroxide slurry/suspension has been widely utilized for Industrial & Marine desulfurization, Waste Water Treatment, Flue gas treatment, Biogas Treatment and Foliar Fertilizer. 

Magnesium/Calcium Salts

Magnesium sulfate, magnesium chloride, calcium chloride are very commonly used magnesium & calcium inorganic salts. Magnesium sulfate is widely used in plant nutrition because it is rich in magnesium and sulfur. Magnesium chloride and calcium chloride benefit from their strong moisture absorption ability, mainly used in snow melt and dust control. Magnesium sulfate and calcium chloride can also be used in aquaculture to provide aquatic animals with magnesium and calcium needed for growth, and to regulate the hardness of water.
