“…The mesh division is performed with 78,040 8-node hex elements (C3D8R). The material properties are shown in Table1 [14][15][16], where the material constants in each composition for finite element analysis, such as Young's modulus, coefficient of thermal expansion (CTE) and Poisson's ratio, are calculated from the mixing rule below [17][18]: 37 8 ) ,…”

The joining of ceramics with metals have been extensively used in applications requiring high strength and excellent heat insulation. However, evaluating the residual stress generated inevitably due to the mismatch in coefficients of thermal expansion of ceramic and metal is challenging, which is very important for fabrication and characterization of layered inhomogeneous material. A simplified analytical model considering the overall deformation compatibility is established to compute the interlaminar residual stresses of the ZrO2/(ZrO2+Ni) sandwich ceramics, which agrees well with the results obtained by the commercial finite element package. The effects of the thickness ratio of the transitional layer to the middle layer, and the number of transitional layers on the properties of the ZrO2/(ZrO2+Ni) sandwich ceramics are researched to obtain the optimal structure.

“…The slip casting technique consists in preparing a water-based slurry of high-density water-insoluble particles of Al 2 O 3 -TiO 2 with the support of auxiliary products such as dispersants, defloculants, additives, and release agents [4,5]. In this method, the process of obtaining the macromembrane takes place in four phases: (i) preparation of the slurry to control viscosity and thixotropy, (ii) putting it into a polymer mold or molding plaster, (iii) demolding and drying, and (iv) sintering by an adequate thermal curve (maximum temperature equal to 1,300˚C).…”

A B S T R A C TAn innovative proposal of tangento-axial filtration based on the concept of macromembrane (large size) is presented in the context of micro-and ultrafiltration ceramic membranes. The macromembrane is made of Al 2 O 3 -TiO 2 by slip casting. It includes an internal system for rotating the fluid trough a propeller which enhances the tangento-axial filtration. This filtration yields better than the cross-flow filtration in conventional extruded ceramic tubes of small diameter. The reasons are, first, its larger sizes relative to the extruded tubular filters, and second, that it can work at higher pressures, resulting in better operational performance. Furthermore, costs of industrial-scale production could be lower. In this study, the conceptual basis, pilot plant, first experimental results, and proposals for improvement of the system to continue the project are presented.
