Porous ceramics which have closes pore were fabricated by heat treatment at 100~600℃ for 30 minutes using dried water glasses with 25, 35 and 45wt% water contents. Size and distribution of the closed pore were varied depending on the water contents and heat treatment temperature. The expansion procedure could be distinguished by two stages ; The frist stage occurred around 100℃ due to the evaporation of water and the second stage occurred at 200~400℃ due to the evaporation of Si-OH compounds. The specimen was not expanded successfully because of the softening of the dried water glass at 500~600℃ |
