The development of novel microporous ceramic membranes for nano-, ultra-, and microfiltration aims to produce cost-effective products with superior mechanical, thermal, and chemical resistance. This study investigates ceramic-based materials topped with aluminumAluminum and zirconium, reinforced with zinc and magnesium compounds, and fabricated using co-precipitationPrecipitation. Cylindrical samples were thermally treated and modified to achieve varied porosities. The research characterized porosity, permeability, and water absorption capacity of all materials. Compared to magnesium, zinc addition significantly increased and controlled porosity density. SEM analysis revealed structural and compositional changes, particularly increased open porosity with zinc addition. Water penetration studies showed that Al–Si–Zr + 30 wt% MgAl-Si-Zr/Mg had the fastest permeability and liquid saturation speed, while Al–Si–Zr + 30 wt% ZnAl-Si-Zr/Zn was slowest. The proposed method determines liquid penetration conditions within ceramic alloys by considering local and non-local parameters, contributing to the development of improved ceramic membranes for filtration applications.

摘要

The development of novel microporous ceramic membranes for nano-, ultra-, and microfiltration aims to produce cost-effective products with superior mechanical, thermal, and chemical resistance. This study investigates ceramic-based materials topped with aluminumAluminum and zirconium, reinforced with zinc and magnesium compounds, and fabricated using co-precipitationPrecipitation. Cylindrical samples were thermally treated and modified to achieve varied porosities. The research characterized porosity, permeability, and water absorption capacity of all materials. Compared to magnesium, zinc addition significantly increased and controlled porosity density. SEM analysis revealed structural and compositional changes, particularly increased open porosity with zinc addition. Water penetration studies showed that Al–Si–Zr + 30 wt% MgAl-Si-Zr/Mg had the fastest permeability and liquid saturation speed, while Al–Si–Zr + 30 wt% ZnAl-Si-Zr/Zn was slowest. The proposed method determines liquid penetration conditions within ceramic alloys by considering local and non-local parameters, contributing to the development of improved ceramic membranes for filtration applications.
