โฆ Synopsis
A porous ceramic that can be used for mechanical seal faces is described. The pores are not less than 5 ยตm, and are compressed into an elliptical shape with the minor diameter parallel to the direction of sliding. The value of the cross-sectional area of the pores relative to a circular pore is defined, as is the pore size distribution.
