PREPARATION AND SINTERING OF W-20%Wt Cu COMPOSITE POWDERS PRODUCED BY CO-PRECIPITATION METHOD
Abstract: materials can be fabricated by sintering of W-Cu composite powders. In this research W-20%wt Cu composite powderswas synthesized via a co-precipitation method. Precipitate obtained from a mixture of copper nitrate and ammoniumparatungstate (APT) in distilled water contained W-Cu compounds. This precipitate was washed, dried and calcinedat 550 of dried precipitate powder was determined...

متن کاملPreparation and Evaluation of NiFe204 and CuFe204 Nanoeatalysts by Combination of Sol- Gel Auto-Combustion Method and Irradiation Technique
The dried nitrate-urea gels exhibit the combination of autoicatatric combustion behavior and ultrasonic, whichcan be used to synthesize the nanocatalyst ferrite powders. Cu and Ni Unites nanocatalyst powders sithcomposition of Caned], and NiFe204 were synthesized by a sol-gel auto catalnic combustion process. Themolar ratio between metal ions and urea was 11.2. The sob gel process was done at 8...
متن کاملEffects of Black Scorpion Androctonus crasicuda Venom on Striated Muscle Preparation in vitro.
Effects of venom from black scorpion Androctonus crasicuda (AC) were determined on isolated chick biventer cervices nerve-muscle and mouse hemidiaphragm preparations using twitch tension method. The isolated nerves were stimulated by electrical stimulator and response to each stimulus was recorded. The venom mainly acted prejunctionally to facilitate neuromuscular activity due to an increase in...
