Embodiment 1
[0033]The red mud raw material and 150g / L sodium hydroxide solution were added to the high-temperature reactor for reaction at a liquid-solid ratio of 5mL / g. The reaction temperature was 300°C, the stirring rate was 300r / min, and the reaction time was 3h. After the reaction was completed, the red mud was dried at 100° C. for 10 h for use. Add 75 parts of red mud pretreated by alkali activation, 15 parts of sodium borate, and 10 parts of starch into a ball mill for ball milling and pulverization. After mixing, sieve through 300 mesh. Add the mixture to the mold and shape it. The molding size is 55mmX6mmX6mm. Melt the mixture together with the mold at 1000°C for 1.5 hours to obtain a uniform foamed glass liquid. Lower the furnace temperature to 700°C and keep it for 1 hour to foam the glass liquid. Crystal nuclei are formed at high temperature again, and then the temperature of the furnace is raised to 850°C for 1 hour to keep the crystal nuclei growing and forming crystals, and...

[0035] The red mud raw material and 180g / L sodium hydroxide solution were added to the high-temperature reactor for reaction at a liquid-solid ratio of 7mL / g. The reaction temperature was 300°C, the stirring rate was 300r / min, and the reaction time was 3h. After the reaction was completed, the red mud was dried at 100° C. for 10 h for use. Add 80 parts of red mud pretreated by alkali activation, 15 parts of sodium borate, and 5 parts of starch into a ball mill to pulverize, mix and sieve through 300 mesh. Add the mixture to the mold and shape it. The molding size is 55mm X 6mm X6mm. Melt the mixture together with the mold at 1100°C for 1.5 hours to obtain a uniform foaming glass liquid. Lower the furnace temperature to 750°C and keep it for 1 hour. Soak the glass liquid at high temperature again to form crystal nuclei, and then raise the furnace temperature to 900°C for 1 hour to keep the crystal nuclei growing and form crystals, and then cool down to room temperature with the...

[0037] The red mud raw material and 180g / L sodium hydroxide solution were added to the high-temperature reactor for reaction at a liquid-solid ratio of 7mL / g. The reaction temperature was 300°C, the stirring rate was 300r / min, and the reaction time was 3h. After the reaction was completed, the red mud was dried at 100° C. for 10 h for use. Add 75 parts of red mud pretreated by alkali activation, 15 parts of sodium borate, and 10 parts of starch into a ball mill for ball milling and pulverization. After mixing, sieve through 300 mesh. Add the mixture to the mold and shape it. The molding size is 55mm X 6mm X6mm. Melt the mixture together with the mold at 1000°C for 1 hour to obtain a uniform foaming glass liquid. Lower the temperature of the kiln to 700°C and keep it for 0.5h. Soak the glass liquid at high temperature again to form crystal nuclei, and then raise the furnace temperature to 850°C for 1 hour to keep the crystal nuclei growing and form crystals, and then cool down ...
