1/5/2019· The bioactivity of Ti metal can be improved by chemical treatments with H 2 O 2 / NaOH and a subsequent heat treatment. Ti-H 2 O 2-Ca-heat retained the bioactivity of Ti metal whereas the same was abated during NaOH-Ca-heat treatment. An anatase TiO 2 with high surface ion exchange property was found to be the key driving force for its bioactivity.

Cas 7789-78-8,CALCIUM HYDRIDE | lookchem
Preparation: The calcium metal is charged in the wok, and it can react with hydrogen to generate calcium hydride when temperature get about 300 with electric or oil. Ca + H2 → CaH2 + 214kJ·mol-1 Or in a stream of hydrogen, magnesium can reduce calcium oxide reduction to get calcium hydride, due to the separation of calcium oxide is difficult, high purity calcium hydride products can not obtain.
