The 29 si mas nmr spectrum of uhm 3 with a low si al ratio shows only one resolved line around 87 ppm figure 5 a.

Al mas nmr. 27 al mas nmr exafs and x ray induced absorption measurements have been carried out in al doped silica as. These three resonances are assigned to the three inequivalent framework positions of leucite. Search for other works by this author on. Mas nmr spectra for the 1h and 27al nuclei have been obtained on a variety of alh 3 samples that include the β and γ phases as well as the most stable α phase.

0 02 wt yb 0 8 wt al 0 4 wt glasses fabricated by mcvd. In addition to the transferrin type resonance additional peaks are seen. Several solid state nmr techniques including magic angle spinning mas and multiple quantum mq mas experiments have been used to characterize various alh 3 samples. 29 si and 27 al mas nmr study of the thermal transformations of kaolinite t.

High resolution 27 al mas nmr spectra of natural leucite recorded at h 0 11 7t contain three resolvable resonances at 27 al δ i 69 2 64 7 and 61 0 0 5 ppm. The aluminated brain tissue has a considerably different 27 al mas nmr spectrum. Fitting the observed spectra yields a si al distribution for leucite in which approximately one half of the. In nuclear magnetic resonance magic angle spinning mas is a technique often used to perform experiments in solid state nmr spectroscopy and more recently liquid proton nuclear magnetic resonance.

0 4 wt al 6 3 wt and yb al doped silica yas. Combination of 27 al mas nmr and xrd data of isolated polycationic species would constitute an interesting approach for species sites identification in solution by 27 al nmr. Alumina is widely used as an industry important multi functional material. For example α alumina is used as a single crystalline substrate for electric devices and γ alumina is as a heterogeneous catalyst support.

Al mas nmr spectroscopy. T3 t2 and t1 respectively. By spinning the sample usually at a frequency of 1 to 130 khz at the magic angle θ m ca. As and yas glasses are found to contain the normal 4 5 and 6 fold coordinated al sites al 4 sup al sup 5 sup and al sup 6 sup.

54 74 where cos 2 θ m 1 3 with respect to the direction of the magnetic field the normally. Relationship between 27 al chemical shifts and al o distance in alo 4 environments. 1 h mas nmr revealed sro impregnation caused a loss or shifting of the terminal and bridging hydroxyl environments with a new peak at 0 5 ppm hypothesised to be a modified oh 4 environment. Spectra for amorphous and crystal alumina.

At increasing si al ratio a second line around 94 ppm becomes resolvable figure 5 b the intensities of both lines increase with increasing si al ratio but the 94 ppm line increases relatively more and dominates the spectrum at a si al ratio of 1 01 figure 5 b to 5 d. In conclusion 1 h 27 al cp mas nmr has shown that doping γ alumina with sro covers alo 5 and alters the surface alo 4 alo 6 ratio.
