Using carboxymethyl cellulose (CMC) as an anti-settling agent of low melting point glass powder aqueous dispersion, the high-pressure homogenizer can refine glass powder particle to reduce their size. Different high-pressure homogenized time affected on glass powder’s particle size and the sintering property. Under the same pressure (50 MPa) a longer high-homogeneous time gets smaller particle size and narrows particle size distribution. And the softening temperature and sintering temperature are also lower. The results show that the high-pressure homogenizer techniques can be used to reduce the particle size of the glass powder, so that the softening temperature and sintering temperature will be lowered.
