Product Description SUOYI Granular PowderDichroite Cordierite for Electronic substrate and Optical field with Factory PriceCordierite is a silicate mineral that usually has a light blue or light purple color, a glassy luster, and is transparent to translucent. Cordierite also has the characteristic of being distinctly polychromatic (trichromatic), emitting different colors of light in different directions. In addition to being used as a gemstone for its high quality and color, cordierite is commonly used as a honeycomb carrier material for automobile purifiers due to its good refractoriness and low thermal expansion. Cordierite is found in schist, gneiss and altered igneous rocks. People therefore also call cordierite dichroic. Magnesia cordierite can be synthesized artificially for use in refractory materials. Raw cordierite typically weighs 4-5 carats, and larger ones have been found. Cordierite is usually cut into traditional shapes and the most popular color is blue-purple.MF:Mg2Al4Si5O18 Product Description Mullite, a silicate alumina refractory, is commonly used in stainless steel precision casting processes.The fireproof degree is about 1750 degrees. The higher the content of aluminum and iron in mullite sand is, the lower the content of iron is and the smaller the dust is, the better the product quality is.Morai sand is made from kaolin sintered at high temperature.Product Features:1. High fire resistance.2. High aluminium, low iron.3. High volume density.4.Small coefficient of thermal expansion.5. Stable physical and chemical properties.6. Fully calcine.7. Low dust content.8. Size standard.Usage Advantages:1. Shell cleaning is easy for casting.2. No casting deformation.3. Good casting brightness and finish.4. High casting yield.Usage Advantages:1. Shell cleaning is easy for casting.2. No casting deformation.3. Good casting brightness and finish.4. High casting yield.Application :1. Products suitable for stainless steel, alloy steel, carbon steel, heat resistant steel, titanium alloy, nickel alloy, aluminum alloy, cast iron, cast copper and other large, medium and small precision castings.2. The products are suitable for precision casting, silica sol precision casting, lost wax casting, casting steel, casting copper, vacuum casting, gypsum filler V casting coating, casting mold shell, etc.It is generally used in stainless steel precision casting process. When the refractory degree is about 1750 degrees, the higher the aluminum content in mulberry sand is, the lower the iron content is. The smaller the dust is, the better the quality of mullite product is.Application of Fused Mullite:Electro-fused mullite is widely used in low creep hot blast furnace bricks, iron water pot bricks, and fish can bricks, high-temperature industrial kiln bricks, glass lining bricks, and high-temperature crucibles, shelves, etc.Advantages of fused mullite sand fused mullite powderIt has the characteristics of excellent thermal shock stability, low creep value at high temperature, high hardness and good resistance to chemical corrosion.

It can be used to prepare porous ceramics with thin porous wall and fast temperature rise, and can be used as catalyst carrier. At the same time, the cordierite ceramics have large specific surface area and strong adsorption capacity, and can adsorb harmful substances. Cordierite is commonly used in ceramic packaging materials, as well as in boron plate and support materials for tunnel kilns.Cordierite can be applied to high temperature flame surface, such as flame nozzle; Can also be used in hot and cold alternating fast heat exchanger, such as heat resistant porcelain, heat resistant pot, etc. The crystal structure of cordierite determines that the crystal can dissolve the oxide of transition element in the solid solution, which results in lattice distortion and high infrared emissivity of cordierite.
