研究了反应烧结和预合成化学计量尖晶石中添加不同氧化物的致密化过程。以氢氧化物为原料，在1400 ℃和1600 ℃下进行spinet的预合成。对于反应烧结产物，氢氧化物也分别在1400和1600 ℃下煅烧以获得类似的反应性性质，然后混合以获得尖晶石组合物。氧化物，即B2 O3，V2 O 5，TiO 2，Cr2 O3和煅烧的共沉淀尖晶石被用作两种类型的尖晶石的添加剂。在1550-1650 ℃的温度范围内进行无压烧结，并对烧结产物进行表征以进行致密化研究。(C)2002年Elsevier Science Ltd和Techna S.r.l. All rights reserved.
Densification of reaction sintered and presynthesised stoichiometric spinels were studied adding various oxides as additives. Using hydroxides as starting materials, presynthesisation of spinet was done at 1400 and 1600 degreesC. For reaction sintered products the hydroxides were also calcined separately at 1400 and 1600 degreesC for similar nature of reactivity and then mixed for spinet composition. Oxides namely, B2O3, V2O5, TiO2, Cr2O3 and calcined coprecipitated spinet were used as additives on both the types of spinels. Pressure-less sintering was done in the temperature range of 1550-1650 degreesC and the sintered products were characterised for densification study. (C) 2002 Elsevier Science Ltd and Techna S.r.l.
