Aluminum Oxide Blasting Media Manufacturers Mexico

The BC line is the solubility curve of Na2O · Al2O3 · 5H2O in NaOH solution, white corundum and the solution at point B is in equilibrium with Al2O3 and Na2O. The solubility of sodium aluminate hydrate in NaOH solution decreases with the increase of NaOH concentration. The equilibrium solid phase of point C is sodium aluminate hydrate and sodium hydroxide monohydrate; point D is the best alumium oxide for glass blasting composition point of NaOH · H2O (53.5% Na2O, 46.5% H2O).

E point is the composition point of Na2O · Al2O3 · 5H2O, brown aluminum oxide factory which is 48.8% Al2O3, 29.7% Na2O, 21.5% H2O. On the de line and its upper right side, there is no liquid phase. The actual Na2O: Al2O3 molar ratio of sodium aluminate solution is not less than or equal to 1. Therefore, the actual composition point of aluminum oxide blast media sodium aluminate solution should be located at the lower right side of the OE line, that is, it can only exist in the scope of the OED area.


For Al (OH) 3 and sodium aluminate hydrate, the solution in this area of obcd area is in an unsaturated state and has the ability to dissolve the two aluminum oxide 180 grit blast media substances. When Al (OH) 3 is dissolved, the composition of the solution will change along the line between the composition point of the original solution and point t (Al2O3 · 3H2O contains Al2O3, 65.4%, H2O, 34.6%), until the intersection of the line and ob line, that is, the brown aluminum oxide 80 grit solution has reached the solution equilibrium concentration.


When it dissolves solid sodium aluminate, the black silicon carbide manufacturers composition of the solution changes along the line between the composition point of the original solution and the positive point of the composition point of sodium aluminate (if it is anhydrous sodium aluminate, it is H point, H point is the composition point of anhydrous sodium aluminate, brown fused aluminum oxide manufacturers Na2O · Al2O3 contains Al2O3, 62.2%, Na2O, 37.8% until the intersection of BC line.


The farther the composition point of the original solution is from the OB line, the greater the degree of unsaturation, 120 grit aluminum oxide and the more Al (OH) 3 that can be dissolved when it reaches saturation. The region of obto is a supersaturated sodium aluminate region of Al (OH) 3. The further the composition point of the original solution is away from the OB line, the greater the degree of supersaturation and the more gibbsite can be precipitated. 


In the decomposition process, the composition of the white fused alumina solution changes along the line between the composition point of the original solution and the t point (the composition point of gibbsite), until the intersection point with the OB line reaches the equilibrium solubility of Al (OH) 3 in the solution. If the right section is extrapolated to low temperature, the intersection point with the left curve is the 100 grit aluminum oxide approximate transition temperature of Al (OH) 3-aiooh.


The solution in this region has the characteristics of decomposition and precipitation of white aluminum oxide gibbsite crystal. The solubility of Al2O3 decreases with the increase of temperature, which is the maximum point of the solubility of Al2O3 in Na2O solution at the intersection of the two lines. This is due to the change of the composition of the solid phase in the equilibrium of na2o-al2o3-h2o system with the change of the silicon carbide 180 grit composition of the solution at different temperatures.
