Enhanced corrosion resistance of magnesia-chrome refractories impregnated with zirconia sol

The thermal debinding of soluble binders in injection molded zirconia ceramic from room temperature to 250°C

“…Zirconia ceramic has emerged as a noteworthy advanced ceramic material during the 5G era, owing to the exceptional strength and toughness, good wear and corrosion resistance, and absence of electromagnetic shielding. [1][2][3][4] Simultaneously, its favorable biocompatibility does not lead to allergic reactions or tissue rejection, making it appropriate for usage in medical and dental domains. 5,6 Nevertheless, ZrO 2 ceramic machining is very difficult for complex shape, which increases the cost of wide application.…”

Optimization of corrosion resistance and mechanical properties of Al2O3‐Cr2O3 refractories for waste incinerator

“…Previous researches showed that the suspensions or colloidal solutions impregnation treatment is one of the effective methods to improve microstructure, mechanical properties and thermal insulation performance of refractories. [23][24][25][26][27] Works by Jin et al showed that the impregnated Si 2 N 2 O porous ceramics with silica sol improved the mechanical properties of refractories due to the reduced surface pores and the increased crack propagation paths. 28 Research by Malaiskiene et al presented that the impregnation of silica sol into fireclay-based castables formed a denser and thinner glassy barrier on the sample surface, and further reduced the penetration of potassium-containing liquid phases, significantly improving the corrosion and penetration resistance to alkaline compounds.…”
