sodium tartrate with or without 0.5 mL/L sodium hypochlorite (solution, 8%–10% valid chlorine content) as shown in Table 2. During anodizing, the temperature of the electrolytes was kept at 25–30 °C... occur, and OH– ions are generated. Therefore, in the solution free from sodium hypochlorite, the following reactions normally occur on the alloy surface [28, 29]: Ti=Ti4++4e– (anodic dissolution) ......
. The main phases of the sinter are 12CaO·7Al2O3 and γ-2CaO·SiO2. The alumina of 12CaO·7Al2O3 is easily leached into sodium carbonate solution. The crystal form of 2CaO·SiO2 of calcium aluminate slag.... And the decomposed silicon dioxide will come into the crude liquor and complicate the desilication system. It has been reported that γ-2CaO·SiO2 is inert in sodium aluminate solution, and it normally does not react......
