The glass formation, crystallization behavior and structure were investigated in the ZnO-Al2O3-SiO2 system. boundaries of forming region are defined, indicating absence glasses along ZnO-SiO2 binary role Al to improve formation. has been clarified for representative compositions showing first willemite near a metastable zinc aluminosilicate solid solution higher Al2O3/SiO2 content. Gahnite appe...
In order to study the interaction of ions of intermediate energies with plasma fluctuations, two plasma immersible lithium ion sources, based on solid-state thermionic emitters (Li aluminosilicate) were developed. Compared to discharge based ion sources, they are compact, have zero gas load, small energy dispersion, and can be operated at any angle with respect to an ambient magnetic field of u...
Very low thermal expansion materials have been developed in a wide temperature range from -150 oC to 450 oC. These very low expansion materials are composed of a lithium aluminosilicate matrix with dispersed silicon carbide nanoparticles. The nSiC content in the most stable composite has resulted to be 27 vol.%. Powder processing and sintering temperature control have been found to be of key im...
