| Description |
The effects of minor additions such as Li2O, ZnO, Al2O3 MgO, NiO etc. on the sintering and grain growth of technical titania from 1100°C to 1400°C have been investigated. The effect of additives varies with the sintering temperature. The linear shrinkage of specimens at relatively lower temperatures is given by the expression (Image Presented) where I represents the diameter of the specimens, t is the time of soaking at shrinkage temperature and k is a rate constant. The variation of K with temperature T (°K) follows an exponential expression k=koe—E/RT where E is the activation energy of sintering. It has been observed that the value of E decreases with minor additions of the above oxides. © 1966 Taylor & Francis Group, LLC.
