This paper deals with densification and alpha - GT p phase transformation Of Si3N4, with a constant beta-Si3N4 seeds concentration regarding sintering temperature and different additive types. The seeds Of beta-Si3N4 were ...

Phonon spectra of Cd1-xMnxS (x = 0; 0.01; 0.05; 0.1; 0.15; 0.3) nanoparticles (d similar to 4.5 rim) have been investigated by far-infrared reflection (FIR) (spectral range 40 - 600 cm(-1), temperature range 80-300 K) and ...

In this paper we used X-ray, far-infrared reflectivity and electron paramagnetic resonance measurements to investigate the optical and magnetic properties of Hg1-xMnxSe (x LT = 0.26) alloys. Also, we used different models ...

X-ray fluorescence and DTA-specific heat measurements were performed on several samples of the Hf-Fe phase system, at 50:50%, and 33:67% concentrations. In the first concentration range the possibility of an ordered compound ...

Phonon spectra of Cd1-xMnxS (x =0; 0.01; 0.05; 0.1; 0.15; 0.3) quantum dots (dsimilar to4.5 nm) are investigated by far-infrared reflection in the spectral range 80 - 600 cm(-1) and temperature range 80-300 K. The Cd1-xMnxS ...
