Abstract

Infrared spectra of two minerals; Urkut quartz (Hungary) and a Swedish feldspar, of different origin with different physical characteristics and crystallinity were studied. Samples were taken after appropriate grinding, and infrared spectra, X-ray powder diffraction and water vapor absorption measurements were made along with electronmicrographs. Quantitative conclusions were drawn from changes of particle size and the ratio of bands of the Si—O groups and also the degree of crystallinity and changes of the particle size, respectively.

Резюме

Резюме

Изучались инфракрасные спектры двух минералов: кварца Уркут /Венгрия/ и Шведского полевого шпата, различного происхождения с различными физическими свойствами и кристалличностью. Образцы были отобраны после надлежащего измельчения, и затем проведены измерения инфракрасных спектров, рентгеновских спектров, полученных порошковым методом дифракции, и измерения абсорбции водяного пара, одновременно с изучением методом электронной микрографии. Были получены количественные данные благодаря изучению изменений размеров частиц и отношения связей групп Si-0, a также степени кристаличнос-ти и соответствующих изменений размера частиц.

Kurzreferat

Kurzreferat

Infrarotspektra zweier Mineralien, Urkutquartz (Ungarn) und ein schwedischer Feldspat, von verschiedener Abstammung mit unterschiedlichen physikalischen Eigenschaften und Kristallformen wurden untersucht. Nach angemessenem Mahlen, wurden Proben genommen und Infrarotspektra, Röntgenpulverdiagramme, und Elektronenmikrographien aufgenommen und Wasserdampfabsorptionen gemessen. Von der Veränderung der Teilchengröße, dem Verhältnis der Schwingungen von den Si-O Gruppen und auch dem Grad der Kristallinität, bzw. der Veränderung der Teilchengröße, wurden quantitative Schlüsse gezogen.
