1. Preparation of magnesia foam ceramic filter, which is used for alloy liquid purification, solves the technical problem of existing technical filter not filtering magnesium alloy and superalloy containing active elements.
2. Magnesium oxide ceramic core shall be prepared at a temperature not less than 1600℃ and shall not react with pouring metal under high temperature. The surface of the casting shall be smooth and the surface roughness shall not be greater than 10 m;
It makes up for the defects of a large number of pores and sand in the inner hole of casting when the material is cast with silicon based core. Excellent solubility, can be well dissolved in weak acid, short stripping time, simple stripping equipment, clean, safe and reliable stripping process, reducing the cost of precision casting; No hot cracking occurs in hollow thin - walled castings. High precision of core size; Have enough strength, in the shape, handling and loading furnace deformation, not broken.
3, high purity magnesium oxide VK-MG05TC together with alumina to prepare molten ceramic particles, can be widely used in the field of abrasive.
4, high-purity magnesium oxide VK-MG05TC and rare earth oxide together as sintering assistant, the preparation of silicon nitride ceramics, can be efficient and economical to manufacture a variety of complex shape products, such as cutting tools, sealing rings, bearings, nozzle and a variety of high temperature, wear resistance, corrosion resistance products.
5, the preparation of high-toughness ceramic materials, high purity magnesium oxide VK-Mg05TC and yttrium oxide or rare earth metal oxide as composite stabilizer fired and heat treatment made of excellent mechanical properties, anti-high-temperature aging part of the stability of zirconia ceramics.
The ceramic material can be widely used as high - temperature engineering parts and high - grade refractories.
Meishen is the world's leading producer of magnesium oxide, Magnesium oxide is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. Magnesium oxide is white or light yellow powder, odorless, tasteless, this product is insoluble in water and ethanol, melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory insulation properties. It can be converted into crystal by burning at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.
Magnesium oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia bricks, refractory materials and moisturizing materials. It is also widely used in rubber, rubber sheet, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, glass fiber reinforced plastics and Surface coating of silicon steel sheet, paper production, steel ball polishing, leather treatment, insulation materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.
Hebei Meishen Chemical Technology Group is the main magnesium oxide producer in the world. It is also the largest magnesium salt producer in China and has won the ISO9002 quality system certification. It also has GMP-Certification.
