Development of Magnesia Spinel brick using Pre-synthesized
Spinel can be used in formation of refractory bricks in combination with magnesia in two ways. In the first method pre- synthesized spinel is taken and mixed with magnesia. In the second method alumina is mixed with magnesia and it results in formation of in-situ spinel.

Analysis and Prediction of Corrosion of Refractory
Oct 23 2020 · In general MgO-based refractory materials are basically free from corrosion reaction in the temperature range below 1200 °C because MgO ions carry two charges and the radii of oxygen ions and magnesium ions are relatively small which causes magnesium oxide to have large lattice energy a high melting point and stable properties .

Ceramic Materials Science and Engineering
Semisilica brick is a silica brick containing between 18 and 25 Al2O3. Fireclay brick is made from kaolinite (Al2O3 · SiO2 · 2H2O) with between 25 and 45 Al2O3. High-alumina brick has an alumina content in the range 45–100 wt . Dolomite brick is made from dolomite (CaCO3 · MgCO3). Magnesia brick contains mainly MgO (typically >90 MgO).

Apr 28 2015 · It has become accepted usage to use the term magnesite-spinel brick to refer to the products containing MgO•Al2 O3 . A family of magnesite-spinel brick has been developed by combining the constituent raw materials in various ways. Some magnesite-spinel brick are made by adding fine alumina to compositions composed mainly of magnesia.

Synthesis of Magnesium Aluminate Spinel Powder from the
Synthesis of magnesium aluminate spinel (MgAl2O4) was investigated by employing ball milling and co-precipitation methods. The starting materials (aluminum hydroxides) were obtained from the purified sodium hydroxide leaching solution of black dross. The characteristics of the synthesized spinel was analyzed through X-ray diffraction (XRD) scanning electron microscopy (SEM) images.
