Abstract: We report the discovery of 8 991 new spectroscopically confirmed white dwarfs and subdwarfs in the Sloan Digital Sky Survey Data Release 10. We obtain Teff, log g and mass for hydrogen atmosphere white dwarf stars (DAs) and helium atmosphere white dwarf stars (DBs), and estimate the calcium/helium abundances for the white dwarf stars with metallic lines (DZs) and carbon/helium for cool carbon dominated spectra DQs. We found 2 new oxygen dominated spectra white dwarfs, 69 DQs, 42 hot DO/PG1159s, 175 white dwarf+main sequence star binaries, 206 magnetic DAHs, 325 continuum dominated DCs, 397 metal polluted white dwarfs, 450 helium dominated white dwarfs, 636 subdwarfs and 6796 new hydrogen dominated white dwarf stars.
