Paper Title:
Influence of Ceramic Aggregate on the Microstructure of Filtration Materials
  Abstract

In this paper, by some technological process, the reusable filtration materials has been made by using the main waste residue of ceramic industry—waste ceramics as the aggregate and mixing with proper binder and pore-forming agent. The production process of filtration materials and the character of light CaCO3 as pore-forming agent were described; For the selected raw materials, changed the ratio and aggregate granularity, the influence of ceramic aggregate content on the aperture, aperture distribution, porosity and bending strength of filtration materials and the influence of aperture distribution of aggregate on sample’s capability have been revealed based on the XRD analysis, SEM observation and bending strength measurement of filtration materials; at the same time, the influence of sintering temperature on the porosity and bending strength of filtration materials was also studied. The results show that the better filtration effect and better chemical durability, the higher bending strength (15MPa) of the synthetical filtration materials can be obtained when the content of aggregate, the particle size and the sintering temperature are respectively 50~55wt%, 150~1804m and 1205°C.
