Dislocation Arrangements in Fluorapatite

Abstract

Some observations on the microstructure of Czochralski-grown fluorapatite, Ca5F(PO4)3, single crystals are presented. From etching and x-ray topographic studies we have found that slip in this material is on (101̄0) planes, with one Burgers vector in the c direction, and another in the basal plane and probably along the [101̄0] direction.
