High-quality SrBi2Ta2O9 single crystals were grown by self-flux solution method. According to x-ray topography the crystals with layered habitus and typical dimensions up to ∼ 7 × 5 × 0.05 mm3 show perfect (001)-orientation with the edges directed along [110] axes. The quality of the crystals was also confirmed by hig…

This paper discusses the possibility of correcting the aberrations of concave holographic gratings recorded by means of supplementary concave mirrors. It is shown that, to compensate 1st-3rd-order aberrations, it is adequate to use a single supplementary cylindrical mirror whose axis lies in the dispersion plane of th…

The effect of crosslink density of unsaturated polyester resin on the corrosion resistance was investigated. Cured unsaturated polyesters with different crosslink density were immersed in pure water and potassium hydroxide solution. Since the weight of resin increased in proportion to the square root of immersion time…

Continuous solid solutions were isolated within the system AICd1-xMIxPO4(AI=Li, Na; MII=Mn, Co) for 0≤x≤1. The steady decrease of the lattice parameters and unit cell volume within the solid solution domains was ascribed to the substitution of Cd2+ cations by smaller size M2+ ions (M=Mn, Co) as the composition progres…
