摘要： Method of producing ceramic-forming oxide powders with variable and predetermined sintering characteristics such as MgO, BaO, Ta 2 O 5 , ZnO. CeO, SnO, CaO, Cr 2 0 3 , CoO, As 2 O 3 , Sb 2 0 3 , ZrO 2 , TiO 2 , ThO 2 , Y 2 O 3 , Si0 2 , UO 2 , Al 2 O 3 , and Ti02. There is a relationship between sintering rate of oxide powders produced from metal alkoxides and degree and nature of hydrolysis. This relationship between the degree of hydrolysis of the corresponding alkoxide and the density of the resulting oxide is determined by hydrolyzing several samples of the alkoxide using different amounts of water in diluted systems. The samples are sintered to produce the metal oxide and its density is measured. A desired density can then be achieved by using the amount of water of hydrolysis which corresponds to that density. Oxide powders with very high rate of sintering characteristics can be achieved by using at least 5 moles of water of hydrolysis per mole of alkoxide.
摘要翻译：具有MgO，BaO，Ta 2 O 5，ZnO，CeO，SnO，CaO，Cr 2 O 3，CoO，As 2 O 3，Sb 2 O 3，ZrO 2，TiO 2，ThO 2，Y 2 O 3，SiO 2，UO 2等的可变且规定的烧结特性的陶瓷形成用氧化物粉末的制造方法， Al2O3和TiO2。由金属醇盐生成的氧化物粉末的烧结速率与水解度和性质之间存在关系。相应的醇盐的水解程度和所得氧化物的密度之间的这种关系是通过在稀释体系中使用不同量的水水解几个样品的醇盐来确定的。将样品烧结以产生金属氧化物并测量其密度。然后可以通过使用与该密度相对应的水解水量来实现所需的密度。可以通过使用每摩尔醇盐使用至少5摩尔的水解水来实现非常高的烧结特性的氧化物粉末。
