An improvement in sintering property of β-tricalcium phosphate by addition of calcium pyrophosphate
TL;DR: CPP-doped beta-TCP ceramics with relative density over 95% could be obtained when sintered at 1200 degrees C for 2 h, and the addition of CPP in the range of 0.5-3 wt% delays phasc transition of beta- TCP and enables sintering of beta

A mechanism for low-temperature sintering
TL;DR: In this paper, the basic mechanism of low-temperature sintering called reactive liquid-phase Sintering has been explained in detail for the case of BaTiO 3, which was sintered to more than 95% of relative density in 15min at 820°C.

Effect of transition metal oxides on densification and electrical properties of Si-containing Ce0.8Gd0.2O2−δ ceramics
TL;DR: In this paper, the effect of TMO addition on the electrical properties of Si-containing CGO20 ceramics was investigated, and it was found that Co3O4 is the most effective sintering aid, and the sintered temperature of CGO 20 can be reduced by over 200 °C by adding 0.5 at.% CoO4/3.

Probing the densification mechanisms during flash sintering of ZnO
TL;DR: Using ZnO as a model system, the densification mechanisms of flash sintering are investigated in this paper, where controlled experiments via limiting the maximum current or the effective ramp rate suggest that both the maximum specimen temperature and the high heating rate are essential for the rapid densification during the flash Sintering, while various electric field/current effects could also exist.

Dopants in Vapor‐Phase Synthesis of Titania Powders
TL;DR: In this article, a gas-phase synthesis of titania by TiCl4 oxidation in the presence of dopants (SiCl4, POCl3, and BCl3) was investigated in an aerosol reactor as a function of temperature and dopant concentration.
Journal ArticleDOI
Microstructural control in the processing of electronic ceramics
TL;DR: In this paper, the influence of powder characteristics, dopant addition, sintering atmosphere, firing schedules and the intrinsic grain boundary properties on microstructural development are discussed, and it is concluded that particle coarsening and rapid grain growth during densification must be minimized, possibly by dopant additions and a control of the sinting atmosphere.
