Summary: In this paper, a novel approach of introducing Al2O3-TiO2 composite powder was proposed to enhance the performances of magnesia with free CaO impurity. The addition of composite powder improved the MgO grain growth and conversion of free CaO to CaTiO3, leading to a reduction in weight gain rate after hydration test. The formed CaTiO3 and Mg1+xAl2(1-x)TixO4 phases enhanced the thermal shock resistance and slag penetration resistance of the specimens, but excessive addition of Al2O3-TiO2 had a negative effect on the slag penetration resistance.

Summary: The study focused on the microstructure and properties of lightweight magnesia refractory castables with porous matrix fabricated by direct foaming method, aiming to improve the energy-saving capacity. Formation of closed-pores in the matrix significantly enhanced high-temperature thermal insulation performance with minor changes of slag corrosion resistance. The thermal conductivity of the lightweight magnesia castables was lowered by 47.8% compared to the referenced castable, but increasing foaming agent content led to decreased density and mechanical performances.

Summary: This study analyzes the influence of calcia refractory purity on the properties of calcia crucibles. Higher purity calcia results in well-developed grains and improved hydration resistance, leading to better high-temperature strength and thermal shock resistance. In contrast, lower purity calcia crucibles exhibit inferior properties. Therefore, high-purity calcia is considered a potential refractory for manufacturing oxide crucibles.

Summary: Lightweight magnesia aggregates were fabricated using high-purity MgO agglomerates with the addition of Mg(OH)2 as a pore former. The addition of Mg(OH)2 influenced the pore evolution, porosity, and pore structure, leading to improved thermal shock resistance and slag resistance at lower Mg(OH)2 content. However, an excessive amount of Mg(OH)2 resulted in the formation of large open pores, significantly deteriorating the thermal shock resistance and slag resistance. Overall, the specimen with 20 wt% Mg(OH)2 exhibited the best performance in terms of thermal conductivity, residual flexural strength ratio, and slag resistance.

Summary: By partially replacing coarse corundum particles with novel porous CMA aggregates in alumina-spinel refractory castables, significant improvements in thermal shock resistance and thermal fatigue resistance were observed, although there was a slight decrease in bulk density and strength. Additionally, slag penetration resistance can also be enhanced with appropriate particle size of CMA aggregates, with the influence strongly dependent on their particle size.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
