Abstract
Capillary ceramic filters were prepared from a quartz-natural zeolite-lead borosilicate glass mixture by uniaxial pressing and sintering at various temperatures. Sintered specimens were characterized by their bending strength, apparent porosity, pore size distribution, and microstructure.The filter sintered at 960°C shows promising engineering properties for the capillary-system: maximum pore size, bend strength and porosity being 0.6 mm, 30 MPa and 33.45%, respectively.
