We propose obtaining TiO2 films by ICPCVD for the fabrication of low-loss waveguides. The challenge is to produce a dense and homogeneous layer with a high refractive index and low absorption in the visible range. Crystallized layers with features su

The ferroelectric perovskite complex 0.93Na0.5Bi0.5TiO3 – 0.07CaTiO3 (NBT –0.07CT) ceramics were studied by a simple X-ray diffraction upon application of an increasing electric field. It is shown that the field induced rhombohedral (R3c) to mono

The joining conditions of alumina (Al2O3) and titanium (Ti) were studied to produce relatively light materials combining a high hardness and ductility at ambient temperature. The starting Al2O3 and Ti in the form of powders were sintered by spark pla
