The present study investigated three lightweight periclase-magnesium aluminate spinel
castables containing microporous magnesia aggregates with a varying apparent porosity …

MgO-based refractories have been regarded as ideal linings for various furnaces owing to
high refractoriness and excellent corrosion resistance to basic slag. However, thermal shock …

Abstract Development of microporous magnesia based aggregates serving as working-line
refractories have great significance in reducing energy loss and saving resource …

Lightweight magnesia aggregates were fabricated using high-purity MgO agglomerates with
the addition of Mg (OH) 2 as a pore former. The pore evolution and its relationship to the …

Two types of MgO-C refractories with tight particle grading and non-tight particle grading
were prepared according to Andreasen's continuous packing theory. Fracture behaviors …

In recent years, there was a huge demand for basic lightweight insulation materials in the
metallurgical industry, especially magnesia‐based refractories with low thermal conductivity …

The rich mineral resources of magnesite have been decreasing rapidly, while the low-grade
magnesite is abandoned, and the requirement on utilization of low-grade magnesite is …

To improve the energy-saving capacity of magnesia refractory castables for working lining of
