Magnesia chrome brick with high purity magnesia and high quality chrome ore as raw material, after high pressure forming and high temperature sintering.
Magnesia chrome brick with good thermal shock resistance and volume stability, used in the cement and glass industries, also Non-ferrous metal smelting furnace.
Magnesia chrome brick is an alkaline refractory product, which is made of periclase and magnesia chrome spinel, and is fired at 1600~1800 °C in an oxidizing atmosphere. It can also be made into non-burned brick by chemical bonding agent such as water glass.
According to the raw materials and process characteristics of the products, it can be divided into silicate-bonded magnesia-chrome bricks, direct-bonded magnesia-chromium bricks, re-combined magnesia-chrome bricks, semi-recombined magnesia-chrome bricks, pre-reacted magnesia-chrome bricks Casting magnesia chrome bricks.
Magnesia Bricks Description
Magnesia Bricks are alkaline refractory materials. These products have over 90% magnesium oxide content and adopt periclase as the principal crystalline phase. Magnesia Bricks can be divided into two categories of Burnt Magnesia Bricks and Chemical Bonded Magnesite Brick. They have excellent performance of superior high temperature mechanical strength and volume stability. Magnesia Bricks can service in the high temperature of 1750.. They are ideal products for glass furnace application.
Magnesia Bricks Features:
It is a kind of alkaline refractory product with periclase as main phase magnesite-alumina spinel clinker as basic material. the product has such characteristics as good temperature vibration, good strength and volume stability in high temperature.

Magnesia Bricks Manufacturing Process
Burnt Magnesia Bricks are manufactured with magnesite clinker as the raw material and fired in the high temperature of 1550~1600 after smashing, burdening, mulling and molding. High-purity products can be fired in the temperature that over 1750. Chemical bonded magnesite brick is produced with certain chemical bonding through mixing, molding and drying.
Magnesia brick is a kind of alkalescency refractory brick that made from the sintered magnesium with its content of 87% and that are combined with silicate. Since its combination composition is mainly cms-m2s system, its load softening temperature is low and thermal shock resistance is poor that determine its application is few. But magnesia brick is widely sued in the furnaces and kilns that have alkaline atmosphere. The essential properties of magnesia brick depends on the nature of the raw materials, the mineral composition, microstructure and closely on the density of the products.
