METHOD FOR CLAY MATTER TEST

摘要

FIELD: physics.SUBSTANCE: minerals are sampled; X-ray fluorescence is excited therein in the optical wavelength range to recognise a mineral; the X-ray fluorescence spectra are recorded for the prepared samples in the wavelength range of 200-500 nm, and kaolin mineral is recognised by luminescence bands in the wavelength range of 290-400 nm with maximum emission at ?=335-357 nm; dickite is recognised by maximum emission at ?=350-370 nm; montromorillonite is recognised by luminescence bands in the wavelength range of 320-380 nm at maximum emission at ?=320-350 nm; pecoraite is recognised by luminescence bands in the wavelength range of 270-400 nm at maximum emission at ?=280-330 nm; nacrite is recognised by a wide X-ray fluorescence band at ?=270-500 nm at maximum emission at ?=340-350 nm.EFFECT: higher expressivity and reliability of clay matter tests.1 tbl, 6 dwg
