Embodiment 1
[0030] First, 2g of sodium aluminate, the chemical formula is Na 2 SiO 3 5g of sodium silicate, 4g of sodium hydroxide and 0.2g of hydrochloric acid were put into 400g of water, and then 0.1g of manganese aluminum silicate was added to form a mixture; then, at normal temperature, the mixture was subjected to 3 Stir for 1 hour; then, put the evenly stirred mixture into a polytetrafluoroethylene material reactor, and after it is completely sealed, put it into a high-pressure reactor, and carry out hydrothermal heating at a temperature of 95°C for 12 hours Synthesis reaction; then, use a center separator to separate the above-mentioned product, and dry the product separated by the center of the center at a temperature of 120°C for 12 hours to form a chemical formula of Mn 2 al 4 Si 5 o 18 The manganese aluminum silicate and the chemical formula is Na 6 MnAl 4 Si 8 o 26 Mixed crystals of sodium manganese aluminum silicate. figure 1 It is an X-ray diffraction analysis diag...
Embodiment 2
[0032] First, put 2g of calcium albumin, 5g of sodium aluminosilicate, 4g of calcium hydroxide and 0.2g of hydrochloric acid into 400g of water, and then add 0.1g of manganese aluminum silicate to form a mixture; Stir the mixture at a speed of rpm for 3 hours; then, put the evenly stirred mixture into a reactor made of polytetrafluoroethylene, and after it is completely sealed, put it into a high-pressure reactor, at a temperature of 95°C The hydrothermal synthesis reaction was carried out for 12 hours; then, the above-mentioned product was separated using a center separator, and the product separated by the center was dried at a temperature of 120 ° C for 12 hours to form a chemical formula of Mn 2 al 4 Si 5 o 18 The manganese aluminum silicate and the chemical formula is Na 6 MnAl 4 Si 8 o 26 Mixed crystals of sodium manganese aluminum silicate.
Embodiment 3
[0034] First, put 2 g of sodium aluminate, 5 g of calcium aluminosilicate, 4 g of sodium hydroxide and 0.2 g of hydrochloric acid into 400 g of water to form a mixture, and stir the mixture for 3 hours at a speed of 2,000 rpm at room temperature; then , put the evenly stirred mixture into a reactor made of polytetrafluoroethylene, and after it is completely sealed, put it into a high-pressure reactor, and carry out a hydrothermal synthesis reaction at a temperature of 95°C for 12 hours; next, After putting 0.1 g of manganese nitrate and 1 g of 0.1 mol hydrochloric acid aqueous solution into the product, put it into a concentrated rotary evaporator, perform ion exchange at a temperature of 90 ° C for 12 hours at a speed of 500 rpm, and then Dry at a temperature of 120°C for 12 hours, and finally cure in air for 2 hours at a temperature of 500°C to form a chemical formula of Mn 2 al 4 Si 5 o 18 The manganese aluminum silicate and the chemical formula is Na 6 MnAl 4 Si 8 o ...
