Distillation method, pine

According to the metal supplier of powders, there are three methods to separate pine forest from steel, a sedimentation method, standard alkali of use thaw or increase alkaline in the test decision so that the huge majority of iron, chrome, manganese, nickel, cobalt, the titan, copper and other interfering elements removed with sedimentation, then dry a part of the filter of the test solution of definition of pine forest. This method is simple, fast, we will apply to division of higher content of pine forest, but cannot remove silicon, aluminum, molybdenum, tungsten and other elements. Distillation method, pine forest classical methods of division.

This method - use of boric acid with methanol to make methanol бората trimethyl B OCH3 3, pine forest and other elements to receive the effective division applicable to more difficult components of high alloyed staly and various other alloys, are the current means of division of the international standard of a method of the basic. The main shortcoming consists that division time long, and a quartz product of requirement. However, if use, glass or plastic devices without pine forest instead of a vessel from quartz, also can, gained the same effect of division. Extraction method, make the pine forest reacting with hydrofluoric acid, BF4 - анион it is created, then adding osnovny dye, such as a dark blue methylene, этил, violet, scintillating green, etc., to make a figurative complex, and then to use two tetrachloroethane, benzene, chlorobenzene and other solvent, to take, achieve the object divisions and colors. Inconvenience - that than 0.5 %, the washing method can use when total amount of niobium, tantalum, makes less to eliminate intervention.
