摘要: Abstract A well-crystalline BaWO4 film has been prepared on a tungsten substrate in an alkaline solution containing barium ions through simple chemical reaction method at room temperature via the between Ba2+ and WO 4 2 − . The acceleration of oxidation/dissolution to form with oxidizing agent, H2O2, seems be key success. Prismatic crystals typical grain size about 8 μm were grown thickness 10–20 after 2–3 hour treatment. effect pH, concentration H2O2 formation studied detail mechanism.
