Magnesium Aluminate Powder

As a refractory material, the MgAl2 O4 spinel has some unique applications such as ceramic or sintered coatings. It is considerably more resistant to slag and to the flows, especially alkaline, of alumina. This spinel, which includes several chemical variations can be used for coat coloration crucibles and nozzles to improve resistance to molten metals and slag. It can be used as an impact-resistant optical window and as an infrared radiation lens. Since this oxide is substantially inert to the cold concentrated mineral acids and also boiling-acid moderate concentration, it would be useful as a dense coating of chemical reactors. Some variants of this oxide include compounds of MgAl2O4 / Al2O3 MgAl2O4 / MgO and solid solutions MgAl2O4 / MgCr2O4. These chemical alterations allow the modification of properties such as thermal expansion and corrosion resistance. Depending on the reactivity of the desired powder, Trans-Tech prepared pure spinel (min 99.0%) and its variants by a variety of techniques between the direct reaction of oxides or salts of ingredients and homogeneous precipitation of the precursor salts (carbonate, hydroxide, and oxalate). ). These techniques provide a variety of powder products with different sizes of crystallite/particles and surface. These materials can be thermally sprayed using powders that react completely to obtain thick and thick coatings having properties close to those of bulk ceramics.
