  Ultraluminous X-ray sources fed by Wolf-Rayet star winds and X-ray bursters
in ultracompact binaries with He or C white dwarfs have accretion disks, whose
properties may significantly differ from those of pure H alpha-accretion disks.
We have therefore included the dependence on charge number Z and mean molecular
weights mu_{e/I} into the Shakura and Sunyaev (1973) scaling relations for the
key parameters of the disk. Furthermore, we also consider the case of the
pseudo-Newtonian potential of Paczynsky and Wiita (1980). These scaling
relations might become useful, e.g., when estimating the illumination
efficiency of the external parts of the disk. We also address the changes in
the structure of the boundary (spreading) layer on the surface of neutron
stars, occurring in the case of H depleted accretion disks.
