A Study on Electroless Deposition of Nickel on Nano Alumina Powder Under Different Sensitization Conditions
This paper deals with the preparation and characterization of Nickel-coated Alumina ceramic particles by Electroless Plating Technique. Nanosized α-Al2O3 powders of about 50nm in diameter are used for plating. The bath for Electroless Nickel Plating is prepared with NiCl2.6H2O, C6H5NaO7.H2O, NH4Cl and NaH2PO2.H2O. A bath temperature of 85°C, pH value of 8 and stirring time of 20 min is consider...
متن کاملSynthesis and Characterization of Alumina Nano-powder Obtained by Sol-gel Method
Este cunoscut că metoda sol gel este una din metodele neconvenţionale de obţinere a pulberilor ceramice. În studiul realizat s-a avut în vedere obţinerea şi caracterizarea de nanopulberi de Al2O3 prin metoda sol-gel, aceasta putand fi un potential material utilizat la realizarea de implanturi biocompatibile.[1,2,3,4] In vederea sintezei s-a pornit de la precursori de natură chimică diferită – a...
متن کاملEffect of pH on the combustion synthesis of nano-crystalline alumina powder
Synthesis of nano-crystalline alumina powder by a chemical pyrophoric reaction using citric acid and ammonia was investigated by varying the pH of the precursor solution, which played an important role in controlling the morphology of the synthesised powder. The flaky morphology obtained at pH = 2 could be modified to fine desegregated particulate form by varying the pH of the solution to 10. T...
متن کاملInfluence of fuel in the microwave assisted combustion synthesis of nano α-alumina powder
Microwave assisted combustion synthesis is used for fast and controlled processing of advanced ceramics. Single phase and sinter active nano crystalline alpha alumina powders were successfully synthesized by different fuel-to-oxidant molar ratios using aluminium nitrate as an oxidiser, glycine as a reducing agents and millipore water as a solvent by microwave assisted combustion synthesis. Ther...
متن کاملNew Method for Preparation of Nano Alumina Powder Using Aluminum(III) Complexes by Combustion Synthesis Without Fuel
Alumina nanomaterials were synthesized via a solution combustion technique using tris-(acetylacetonato) aluminum(III) complex (1) and tris-(2-formylphenolate) aluminum(III) complex (2) at 600, and 1000 °C for 3h. The obtained data showed that the procedure without using fuel resulted in a better phase and morphology. To investigate the phase formation, powder X-ray diffraction technique was use...
