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 کاملSYNTHESIS OF AL2O3-NI COMPOSITE POWDERS BY CO-PRECIPITATION METHOD
The synthesis of micro-sized, uniformly distributed Al2O3-15Vol% Ni powders were studied through three step co-precipitation of hydroxides mixtures from proper solution, calcination at air atmosphere and final step of calcined powders in a carbon bed. Al and Ni hydroxide and amorphous phase were first obtained from their salt’s solutions through chemical co-precipitation method by adjusti...
متن کاملbuckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Surfactant Effect on the Synthesis of B4C-nano TiB Composite by Co-precipitation Method
Titanium diboride is one of the candidate materials for high temperature applications and also for control rod elements in high temperature reactors. This paper presents the experimental data on the composites of B4 C-nano TiB2 that were synthesized successfully by co-precipitation methodat 1523K. Titanium tetraisopropanol, boron carbide, isopropanol and triton x-100were used as the precursor m...
متن کاملPreparation of lanthanum- p-alumina with high surface area by a homogeneous precipitation method for use as catalyst support
Samples containing mixtures of 5 mol % La203 and 95 mol % Al203 were prepared by homogeneous precipitation method with or without the presence of various anions, and calcined at different temperatures in the range of 873-1473 K. Sample prepared by urea hydrolysis in the absence of anions, and calcined at about 1273 K results in the formation of pure lanthanum-,8-alumina (LBA) with high surface ...
