Processing of Porous Ceramics Using Aluminium Derived Binders and Sacrificial Porogen Leaching Method

Abstract:

Porous ceramics was successfully fabricated by a sacrificial porogen leaching method using in-situ synthesised aluminium based binders by reaction bonding at low sintering temperatures of 600-1000°C. Porous ceramics with porosity in the range of 27 to 65% were obtained by leaching technique. Interconnected bimodal pores were produced by both stacking of starting particles and leach out of salt. During sintering, the aluminium binder experienced metal to ceramic transformations and act as good binder.
