It is developed the technique for determination of water impurity in the raw material for sapphire crystal growth by means of K. Fischer method. It is studied the possibilities of water extract analysis and it is developed the technique for express control of ? and ? aluminum oxide charge for Na, K and Ca content be means of flame atomic emission spectrometry. It is improved the multielement atomic-emission technique for determination of Cu, Mn, Fe, Ga, Mg, Mo, Cr, Bi, Ni, Pb, Sn, V, Ti, Co, Si microimpurities in -aluminum oxide and leukosapphire single crystals.56355635 Product Description popup.authors popup.nrat_date 2020-04-03 Close
