A melted layer formed on the surface of silicon carbide particles
and bonded the particles together. The bonding effects between the melted phase and the silicon carbide decided the compressive strength of the samples. The compressive strength
increased rapidly and then decreased slowly with the increasing
of sintering temperatures. Maximum compressive strength of
48.6 ± 3.1 MPa was obtained for the samples sintered at 1400 C.
We hope both the filtration fineness and filtration velocity can be
obtained after covering the samples with thin coatings with
smaller-pore structure. This work is being investigated
