Abstract: FIELD: analytical methods in well drilling technology. 
     SUBSTANCE: invention relates to a method for separately determining magnesium oxide, hydroxide, and carbonate in caustic magnesite powders for use to check composition of magnesite powders used as binding agents in cementation of wells. Method comprises sampling, transferring magnesium compounds into solution, and determining total content of magnesium ions in sample. In the first sample, magnesium compounds are dissolved in 6-7% acetic acid on reflux for 30-40 min and summary content of magnesium ion provided by initial magnesium oxide, hydroxide, and carbonate is determined using trilonometric technique. When dissolving magnesium compounds in the second sample, these compounds are subjected to hydration at stirring at ambient temperature followed by adding excess ammonium chloride and heating reaction mixture at stirring to 60-70°C for 1 h, after which content of magnesium ions provided by initial magnesium oxide and hydroxide are determined trilonometrically. This data allows calculation of magnesium carbonate taking into account total content of magnesium ions determined in the first sample. Third sample is dried to constant weight at 140-150°C, calcined to constant weight at 400-450°C, and calcination loss value is then found from weighting data. Calcined product is transferred into solution as in case of second sample and, using trilonometric technique, summary content of magnesium ions is determined, which allows calculation of content of magnesium hydroxide in initial powder. 
     EFFECT: enabled separate determination of three magnesium compounds when present simultaneously.
