Thermal Conductivity and Bending Strength of Porous Mullite Ceramics Made by PFA Method Using Corn Starch
Porous ceramics are widely used in filter, thermal insulation and acoustics applications. This research aims to produce porous mullite ceramics by PFA (Pore-Forming Agent)method using corn starch as the agent. Various contents of corn starch of 0, 5, 10, 15, 20 and 25 % weight were added to kaolin p...
