    Abstract:

    A recipe is given for the polishing of precise surfaces oncrystals of bismuth silicate (BSO) and bismuth germanate(BGO). Using this recipe, crystals having surface figure betterthan 1/10 wave, roughness of 20-50 Å rms, and laserquality parallelism (10 arcsec or better) were obtained withabout 1-2 hours effort.

    Washing, Drying, and Ignition of Precipitates

    After filtration, the precipitate is washed to remove coprecipitated impurities and any remaining mother liquor. Colloidal precipitates, such as silver chloride, are washed with an electrolyte (such as dilute nitric acid) to prevent the peptization of the precipitate. In the case of slightly soluble precipitates, the wash solution contains a common ion to reduce solubility. Lead sulfate, which is slightly soluble in water, is washed with dilute sulfuric acid. Similarly, wash solutions may be...
