“…Cordierite honeycomb with porous body has a great advantage in the eco-industrial applications such as catalyst carrier for automobile and high temperature gas filter [1]. Among ceramics filter support materials, such as titanium alumina, mullite, zirconia, spodumene, and cordierite, cordierite is known as a good candidate material due to its high thermal shock resistance and low thermal expansion coefficient [2,3]. Because cordierite has a limitation in low mechanical properties, many research works are still carried out to improve the mechanical properties using second particle reinforcement [4,5].…”

The enhancement of physical properties of porous honeycomb filter for air purification was investigated using cordierite with the addition of pore former and zirconia additive. Because cordierite honeycomb has porous body, binder formulation was varied using graphite for a pore forming agent as well as lubricating agent during the extrusion process. Also, the effect of zirconia additives on the resultant physical properties of honeycomb filter such as porosity, thermal expansion coefficient and mechanical strength was investigated.

“…Adding a nucleating agent to the glass is a popular way to induce an internal crystallization and to increase the degree of crystallinity in the glass [2,3]. Another method that increases the degree of crystallinity of glass is the 2-stage heattreatment method in which the nucleation is induced first at a lower temperature followed by development of crystallization at a higher temperature [4].…”

Abstract. The crystallization behavior in glass-ceramics of a cordierite composition was studied. Parameters were concentration and etching time of the HF solution. Compared to a pure specimen, the glass frit specimens etched with HF solution showed increased crystalline peak intensities of thecordierite phase in the XRD pattern. The crystal size in the glass matrix also increased with an increasing concentration of the HF solution for the etched glass frit. For the glass-ceramics etched with HF solution of various conditions, the -cordierite phase is more favorable for generation than the -cordierite phase. The microstructure and ratio of the crystallinity of the -cordierite phase over the -cordierite phase can be adjusted by changing the HF-etching conditions followed by a firing process..
