Controlled sintering of MgO and Al2O3 powders eliminates sintering aids while achieving dense cubic spinel with strong corrosion resistance.
Pressure-assisted sintering and pre-densification produce large high-purity MgAl2O4 bodies with high density and plasma erosion resistance.
A surface-rich magnesium aluminate and boron layer helps alumina ceramics resist thermal shock, corrosion, and strength loss at high temperature.
Staged calcination of metal salts and urea raises g-C3N4 composite yield while limiting manufacturing complexity and cost.
