systems of sintering additives were used in this study. Kept the proportion of Si to SiC of 7 to 3, and Al from 0 to 8. The starting powders were mixed for 2 h using absolute alcohol solvent in a steel... (AlN-Si3N4-SiC) composite ceramics were prepared to increase the bending strength and improve the phase structure of Si3N4-based ceramics. The ceramics were made by reactive sintering in N2 atmosphere at 1 360......
Preparation and sintering properties of zirconia-mullite-corundum composites using fly ash and zircon MA Bei-yue(马北越), LI Ying(厉 英), CUI Shao-gang(崔绍刚), ZHAI Yu-chun(翟玉春) School of Materials..., zircon and alumina powder by a reaction sintering process. The phase and microstructure evolutions of the composite synthesized at desired temperatures of 1 400, 1 500 and 1 600 °C for 4 h were......
Effect of Y2O3, CeO2 on Sintering Properties of Si3N4 Ceramics 王黎1,苏盛彪1,李竟先2,包亦望1 (1.Key Laboratory for Advanced Ceramics, China Building Material Academy, Beijing 100024, China;2.Department of Materials Science, South China University of Science and Technology, Guangzhou 510641, China) Abstract:The effect of rare earth oxides Y2O3 or CeO2 on sintering properties of Si3N4 ceramics was studied......

of copper acetate, sodium acetate and methane sulphonic acid was dealt. Thamine hydrochloride (THC), saccharin and 4-amino-3-hydroxynaphthalene 1-suphonic acid were used as additives in depositing electrolytes. The cathode current efficiency was calculated using the Faraday’s law. Metal distrbution ratio of the solutions was determined using Haring-Blum cell. These additives impact the surface......
