Methods of Extracting Fine Precipitates

Figure 2: Methods of extracting fine precipitates.

Table 1 is a summary of the methods of extracting precipitates : chemical dissolution and electrolysis. The current standard method is the extraction in a potentiostatically controlled nonaqueous electrolyte solution. Oxides and aluminum nitride are extracted by the iodine methyl-alcohol method.
