In medium concentration slurry, horizontal shear hinders the formation of flow channel, thus significantly reducing the maximum settling velocity(silicon carbide companies). When the concentration of solid is very thin, and they are distributed in the liquid far away from each other and settle in the liquid as a single settling entity(black silicon carbide manufacturers). However, Misra thinks that the effect of this kind of erosion nucleation is significant only at high stirring rate.

N. Brown gave the favorable conditions for nucleation, i.e. high supersaturation, low temperature and low specific surface area of seeds(green carborundum). Eliminate the influence of organic matter. However, due to the complexity of the structure of sodium aluminate solution and the particularity of its behavior(aluminum oxide abrasive), a complete decomposition theory has not yet been formed, and some viewpoints are still in dispute.(white aluminum oxide dental wholesale suppliers italy)


The decomposition of sodium aluminate solution releases a considerable amount of product heat(white fused alumina). In the aspect of decomposition mechanism of sodium aluminate solution, scholars at home and abroad have carried out research for many years and accumulated a large amount of literature, the aggregates are isolated from each other(aluminum oxide grit), which makes people's understanding of the decomposition process deepen gradually.


(white aluminum oxide dental wholesale suppliers italy)Therefore, it is still an important topic in alumina production to study the seed separation process in theory and explore the effective way to strengthen the process in practice. Because there is no bridge between flocs, there is also a lack of necessary time and height to promote the formation of channel. At present, there is no consistent conclusion on the mechanism of these four processes(glass beads manufacturers). The details are as follows.


According to the true solution theory of sodium aluminate solution(white corundum), the induction period is shortened when the initial supersaturation increases, the seed surface area increases and the crystallization temperature increases(garnet abrasive price). Early researchers believed that the decomposition of aluminum hydroxide in supersaturated sodium aluminate solution was the coagulation process of aluminum hydroxide colloidal particles in the solution.(white aluminum oxide dental wholesale suppliers italy) 


For example(brown fused aluminum oxide), Kuznetsov proposed the decomposition mechanism of supersaturated sodium aluminate solution according to the theory of complex ion structure of sodium aluminate solution and the layered structure of gibbsite. However, the addition of fine seeds often leads to product refinement(chemical process), but with the denial of colloidal structure theory of sodium aluminate solution(glass bead abrasive), this view lost its basis.


(white aluminum oxide dental wholesale suppliers italy)The "mixing theory" of the structure of sodium aluminate solution (that is(black corundum), the existence of aluminum hydroxide colloidal particles and aluminate ions in the solution) divides the decomposition of supersaturated sodium aluminate solution into two stages, namely(steel shot abrasive), the hydrolysis of aluminate radical and the condensation of aluminum hydroxide colloidal particles produced by hydrolysis. 


The hydrolysis of supersaturated sodium aluminate solution is composed of hydrolysis and crystallization process(physical process)(pink corundum). The formation of the induction period is due to the dynamic results of the nucleation rate dependent on supersaturation and seed surface area. The nucleation of Bayer process is regenerative nucleation(aluminum oxide 180 grit blast media), which is mainly affected by temperature, supersaturation and seed surface condition.
