In the work a chemical synthesis using the sol-gel method was carried-out to prepare alumina powder from aluminium nitrate Al (NO3)3,9H2O. Then AgNO3 was well mixed with the prepared ¿-Al2O3 powder in aqueous solution followed by evaporation and heating, to get 5 and 12 volume percent of Ag in the Al2O3-Ag mixture. A conventional powder metallurgical route was followed to prepare Al2O3-Ag composite pellets. First PVA was added as binder with the mixture, and then the powder was compacted in a circular shaped hole die-punch assembly at certain uni-axial pressure for the samples in a hand press to prepare disc pellets of size 16 mm diameter and thickness of ~6mm and ~3mm . The pellets were first dried at 500°C for 2 hours to burn off the PVA, then pre- sintered at 950°C for 2 hours and finally sintered at 1600°C for 2 hours as soaking time in a furnace.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786202272391\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786202272391","offer_id":39455657459805,"sku":"9786202272391","price":35.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/16965a8e-b336-433e-b3d9-025fe96b9280.jpg?v=1776924198","url":"https:\/\/shop.autorenwelt.de\/products\/preparation-of-metal-toughened-ceramic-tool-material-von-suprakash-mondal-ashim-guha","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
