 Abstract
 PDF
- Aluminum nitride (AlN) powders were prepared by the chemical vapor synthesis (CVS) process in the AlCl_3-NH_3-N_2 system. Aluminum chloride (AlCl_3) as the starting material was gasified in the heating chamber of 300°C. Aluminum chloride gas transported to the furnace in NH_3-N_2 atmosphere at the gas flow rate of 200-400ml/min. For samples synthesized between 700 and 1200°C, the XRD peaks corresponding to AlN were comparatively sharp and also showed an improvement of crystallinity with increasing the reaction temperature. In additions, the average particle size of the AlN powders decreased from 250 to 40 nm, as the reaction temperature increased.

Abstract

- Colored tantalum oxy-nitride (TaON) and tantalum nitride (Ta_3N_5) were synthesized by ammonolysis. Oxygen deficient tantalum oxides (TaO_1.7) were produced by a titration process, using a tantalum chloride (TaCl_5) precursor. The stirring speed and the amount of NH_4OH were important factors for controling the crystallinity of tantalum oxides. The high crystallinity of tantalum oxides improved the degree of nitridation which was related to the color value. Synthesized powders were characterized by XRD, SEM, TEM and Colorimeter.
