  • Abstract
    The etching behaviour of differently oriented LGS plates in aqueous H2SO4 solution was studied. Variations of the etch rate of Y+θ plates with the angle of cut θ have been determined. Orientation effects in out-of-roundness profiles related to various LGS crystalline plates have been analysed in terms of crystal symmetry. Changes in surface texture of etched plates with orientation have been investigated. All the experimental results call for a dissolution process governed by orientation. However the observed anisotropy is different to that related to crystalline quartz.
