問題点があった。(Conventional problems) Conventional porous ceramics of this type are all 1250
Because it is a porous porcelain fired at a high temperature of less than 20°C, it cannot be used as a ceramic filter because it becomes vitrified depending on the raw material and the pores become closed cells, and it cannot be used as a ceramic filter. However, due to the high temperature firing, the large shrinkage rate caused the pores to become irregular, resulting in uneven quality.
