dc.description.abstractFour glass compositions for dental glaze on zirconium ceramics were melted at temperature at 1200oC in corundum crucible with hold for 2 h at maximum temperature and rapidly cooled in water. The following raw materials for melting of the glasses were used: sodium feldspar, potassium feldspar, sodium nitrate, barium carbonate, lithium carbonate, boric acid and biogenic hydroxyapatite (BHA). The glass composition 1 does not contain hydroxyapatite. The other compositions (2, 3 and 4) contain 10, 20 and 30 wt. % BHA, respectively, which partially replaces sodium and potassium feldspars. The biogenic hydroxyapatite powder (BHA) was synthesized by us from Black Sea Rapana venosa shells and monocalcium phosphate monohydrate Ca(H2PO4 )2.H2O by solid-state synthesis at 1180oC. With the present study by methods of XRD, FT-IR-ATR and Fluorescence analysis, we prove that 10 mass % BHA can participate in the composition of glass for dental glaze on zirconium ceramics in the place of feldspars, which would increase its bioactive properties and optical properties.
