Product introduction of magnesia-zirconia bricks
Magnesium-zirconium bricks use high-purity fused magnesia and
synthetic magnesia-zirconia bricks sand as raw materials. After
high-pressure molding and high-temperature firing, they have
excellent corrosion resistance to alkali metals, oxides and
sulfides. The product is made of fused magnesia sand and zirconium
sand and their alkaline materials. The product has a high density
(bulk density) greater than 3.08 g/cm3). It also resists alkaline
corrosive atmosphere and alkaline slag corrosion and is widely used
in glass melting furnaces, regenerators, cement kilns, electric
steel furnaces and non-ferrous metal smelting.

Characteristics and application of magnesia-zirconia bricks brick
The magnesia-zirconia bricks brick is a two-phase eutectic
composite material composed of MgO and ZrO2. Magnesium-zirconium
brick production process The production of magnesia-zirconia bricks
bricks uses magnesia-zircon sand as raw materials to produce
materials with uniform distribution of MgO and ZrO2. This type of
material is to first synthesize magnesia zircon sand. It is to
obtain sintered/fused magnesia zircon sand after mixing MgO and
ZrO2 raw materials as required-fine grinding-ball (blank)-sintering
/ electric melting. Then the magnesia-zirconia bricks sand is
crushed, smashed, classified, batched, mixed, formed, and fired to
obtain a ZrO2 composite magnesia refractory material with uniform
MgO/ZrO2 distribution. It can be seen that their production process
is the same as that of magnesia refractories. ZrO2 is combined with
magnesia to produce magnesia-zirconia bricks bricks. The production
method of this type of material is to mix ZrO2 into magnesia to
produce ZrO2 composite magnesia refractory materials with different
MgO/ZrO2 ratios. Their production process is basically the same as
the production of magnesia-chromium refractories. Special
magnesia-zirconia bricks bricks. The production process of this
type of material is different from ordinary magnesia refractory
materials in that the surface of the magnesia refractory material
aggregate particles is coated with a refractory material with ZrO2
as the main component, and the surface of each particle is
uniformly formed into a thin The ZrO2 coating is dried and fired to
form a strong ZrO2 sintered layer between the periclase particles.
The product has good performance. The material does not produce
cracks, cracks, peeling, and good thermal stability during use. The
magnesia-zirconia bricks bricks with 20% SiO2 content actually
belong to the MgO-2MgO·SiO2-ZrO2 refractory. The combined matrix
layer in the material has high corrosion resistance. The corrosion
resistance of this brick has been confirmed in the use of
regenerator and melting chamber.
