“…From the recorded amplitudes of sections of the continuous spectrum free from atomic lines and molecular bands, the Planck temperature of the bottom surface of the powder mixture was determined by Wien's displacement law [41]. The temperature was calculated to be 1500-1350 ± 200 K during the first 8 ms of the plasma chemical process.…”

An original plasma chemical process initiated by microwave discharge in a mixture of metal and dielectric powders was applied to prepare specific materials, which consisted of microsized spherical particles of aluminum oxide covered with silver nanoparticles. The prepared materials are highly uniform in shape, size distribution, and composition. Their cytotoxicity was investigated using the human cell lines MCF7, HEK293T, A549, and VA-13 and the bacterial strains E. coli JW5503 (ΔtolC) and E. coli K12. Their cytotoxicity was found not to exceed the cytotoxicity of the starting materials. Thus, the prepared materials can be considered highly promising for catalysis and biotechnology applications.

As a result of interaction under normal conditions in an air atmosphere of a microwave pulse of a gyrotron with a mixture of Al/Al2O3 powders, ceramic particles of morphology microprocesses are synthesized. A variant of a multi-stage process for the development of physical and chemical processes in a reactor, taking into account ignition. After the end of the microwave pulse, a cloud is observed consisting of hot aluminum oxide particles and burning aluminum particles. A certain influence of the combustion process of aluminum particles on the products of plasma-chemical synthesis. The paper also determines the average velocity of particles from the powder mixture, the burning time of aluminum particles, the surface temperature of the particles of the powder mixture, and the temperature of the gaseous medium in the upper part of the plasma-chemical reactor.

A new micro-furnace for in situ high-temperature single-crystal X-ray diffraction measurements

et al. 2015

A new micro-furnace equipped with an H-shaped resistance heater has been developed to conduct in situ single-crystal X-ray diffraction experiments at high temperature. The compact design of the furnace does not restrict access to reciprocal space out to 2 = 60 . Therefore, unit-cell parameters and intensity data can be determined to a resolution of 0.71 Å with Mo radiation. The combined use of mineral phases with well characterized lattice expansion (e.g. pure Si and SiO 2 quartz) and a small-diameter (0.025 mm) K-type thermocouple allowed accurate temperature calibration from room temperature to about 1273 K and consequent evaluation of thermal gradients and stability. The new furnace design allows temperatures up to about 1273 K to be reached with a thermal stability better than AE5 K even at the highest temperatures. Measurements of the lattice thermal expansion of pure silicon (Si), pure synthetic grossular garnet (Ca 3 Al 2 Si 3 O 12 ) and quartz (SiO 2 ) are presented to demonstrate the performance of the device. Its main advantages and limitations and important considerations for using it to perform high-temperature diffraction measurements are discussed.
