Microscopy study on the sintering-reaction process of corundum and zircon mixture with MgO additive;

Hydrogenated amorphous silicon was deposited by PECVD, followed by annealing in vacuum The IR transmittance spectra were discussed regarding of SiH configuration and hydrogen content in the material Considering hydrogen release, metaloscope was used to observe the morphology of samples, which were deposited at different experimental condition and followed by annealing.

The anodic processes of irondectrode in sulhric acid sohtions are studied by using photomicrography and SEM techniques.

The influence of reaction pressure on the growth of diamond film is analyzed by using CH3CH2OH and H2 to serve as pressure source,the microwave plasma CVD to accumulate diamond film,the metallographic microscope(×400) to obseve the accumulation effect,and the X-ray diffraction to detect the quality of the film.

With the development of automobiles, materials and other industrial sectors, thedemand of metallographic microscope is growing significantly, especially the automaticmetallographic microscope which has high magnification and high degree of automa-tion.
