When magnesite is calcined at 800-1200â??, it is called "light burning", and its product is called light burning magnesium powder, which is called light burning powder for short. Light-burned powder is mainly used to make cementitious materials, heat-insulating and sound-insulating building materials and ceramic raw materials, and it is also an ideal raw material for producing high-density magnesia. After chemical treatment, light-burned magnesium can be made into a variety of magnesium salts, which are used in magnesium sulfate, light magnesium oxide, inorganic glass fiber reinforced plastic, magnesium hydroxide, fire-proof board, magnesia-alumina spinel, light-weight wallboard, greenhouse bracket, ventilation pipeline, fire-resistant cable, magnesite manhole cover, mold, trailer, and so on.

High purity Magnesia is selected from natural super grade magnesite and purified by flotation ,then made by light burning, fine grinding, pressure ball, calcined in ultra-high temperature oil shaft kiln. It is a high quality raw material for brick making and amorphous refractories.

Dead burnt Magnesia Re-burned magnesia is made of natural magnesite and calcined in high temperature shaft kiln. It is the raw material for making bricks and producing unshaped refractories, and the finished products are used for steel making, electric furnace bottom and ramming furnace lining.

Fused Calcium Aluminate Fused Calcium Aluminate is fused in the electric arc furnace with the high quality raw materials. It is an indispensable refining agent in the process of refined steel making in steel industry. It is characterized by very strong desulfurization and deoxygenation, low melting point,high melting speed, it can shorten smelting time, reduce the energy consumption,reduce dust pollution in the steel plant, and good safety performance,good arc burying effect, reduce the erosion of lining by the arc, increase the service life of the ladle. This product does not absorb the water, does not powder, and easy to store and transport.

Expanded perlite is a kind of natural acidic glassy volcanic lava, a non-metallic mineral. Xinaynag Zhongzhou is the world's best quality perlite producer. Horticultural Perlite Agricultural Expanded Perlite: Horticulture perlite ore is expanded or popped by rapid, controlled heating, it expands up to 15 times its original volume and takes on a foam-like cellular appearance â?? essentially clusters of microscopic glass bubbles, creating a porous structure. This physical transformation makes expanded perlite an extremely effective aggregate for use in horticultural growing mixes â?? or, by itself, as a medium in hydroponic growing and as a rooting medium. Size: 3mm-6mm Usage: 1. Grow seeds and nodes 2. Produce seeding 3. Cultivation in greenhouses 4. Hydroponic Cultivation 5. Turf and landscaping 6. Growing media for indoor and outdoor gardening

Note: Chemical composition, size and packing of above mentioned products can be adjusted according to customer's requirements. Characteristics 1. The quantity of eutectic cell wonâ??t be increased dramatically when chilling reduced. Therefore, casting loose tendency which increased due to inoculation will be reduced and compactness and anti-capacity of castings will be improved. 2. Good section uniformity and recession-proof ability. 3. Low melting point, high solubility, low calcium, little slag and low inoculation temperature is allowed. 4. Little quantity added but significant inoculation effect. Application 1. It is used in thin wall parts which have requirements for dispersed shrinkage and bleeding and uneven thickness castings such as piston ring, air conditioner compressor parts, cylinder block and head, etc. 2. New inoculant which applies to foundry production. It can be used as inoculants as gray iron and ductile iron castings and has significant effect on improving the mechanical property of casting products.

Characteristics 1.Ferro Silicon Magnesium Alloy is shaped in gray lump with metal luster. It is solid and brittle so that it is easy to be smashed. 2.With stable reaction, the absorption rate of Mg. will be increased which is helpful for getting high-quality casting products. 3.High mechanical strength and strong deoxygenation and desulfuration effects.

Sea mineral particles are a kind of porcelain balls made of high polymer materials which can emit specific wave and long-term infrared rays and contain organic germanium, a natural trace element beneficial to human body. Pour the sea mineral particles into the bucket, add about 40â?? warm water people barefoot on the above. Can massage each corresponding tissue system of the foot to produce reflection area of the foot, accelerate the foot microcirculation, increase the blood flow rate of the whole body; At the same time, under the action of trampling at a certain temperature, the sea state particles in the bucket release negative oxygen ion far infrared ray and the water molecules in the body cells to produce effective resonance effect and significant temperature control effect principle, play to adjust nerve reflex, adjust endocrine, enhance the immune system function; For hypoxia caused by increased mental stress, increased blood viscosity, obesity, insomnia, loss of appetite, rheumatism, rheumatoid, endocrine disorders subhealth people......
