By dry crush way, the bulk chiral crystal was smashed to chiral micro-crystal which particle size was 70μm. The chiral micro-crystal was disseminated homogeneously in the gel by sol-gel process. So sol-gel glass containing chiral micro-crystal which thickness was 4 mm has been manufactured successfully. It was found that sol-gel glass containing chiral micro-crystal displayed its depolarization effect. We replaced the chiral micro crystal by glass powder which particle size was also 70 μm, and manufactured the sol-gel glass containing glass powder by the same way. It was found that the sol-gel glass containing glass powder displayed its polarization-held characteristic. The cause was analyzed.
