  text: We study the DC conductivity in potassium titanyl phosphate (KTiOPO4, KTP)
    and its isomorphs KTiOAsO4 (KTA) and Rb1%K99%TiOPO4 (RKTP) and introduce a method
    by which to reduce the overall ionic conductivity in KTP by a potassium nitrate
    treatment. Furthermore, we create so-called gray tracking in KTP and investigate
    the ionic conductivity in theses areas. A local unintended reduction of the ionic
    conductivity is observed in the gray-tracked regions, which also induce additional
    optical absorption in the material. We show that a thermal treatment in an oxygen-rich
    atmosphere removes the gray tracking and brings the ionic conductivity as well
    as the optical transmission back to the original level. These studies can help
    to choose the best material and treatment for specific applications.
