“…The poor result with binder may have resulted from binder burnt out during sintering where heating rate of 10°C/min might have caused rapid vaporization of binder which can cause pores within samples. Moreover, the binder residues may have hold porosity which block better densification while sintering [8][9]. Sample A with no latex binder achieved the highest sintered density which is 3513.09 kg/m 3 .…”

In the processing of semiconducting electro ceramic materials the use of appropriate binder can lead to improve characteristics of powder which will reduce density gradient in the green body during compaction. The binder system is anticipated to have an influence on the grain growth and microstructure which in turn affect the electrical performance. To investigate this phenomenon, TiO2 powder doped with tungsten oxide (WO3), silicon oxide (SiO2) and bismuth oxide (Bi2O3) was processed with and without various percent of latex binder. The prepared samples were characterized by evaluating the physical properties like green density, fired density, axial and radial shrinkage, micro hardness and compressive strength. It was observed that TiO2 processed with latex binder exhibited higher green density and less axial and radial shrinkage compared to powder processed without binder. However, the binder level did not have any significant influence on the other characteristics of varistor discs. SEM analysis indicated that the average grain size was also influenced by the percent of binder used and but the higher average grain size was obtained for discs without any binder.

“…Thus, there will be fewer flaws in compacted green discs which will result in lower radial shrinkage. High sintered density results in low radial shrinkage [12][13][14] which is directly related to non-uniform packing density.…”

A mathematical link is created between green body mass homogeneity and sintered component dimensional scatter. In the light of the model, data from die pressed and injection moulded powders are analysed for green mass variations and sintered size variations. The model provides guidelines for assessing research needs for process control, green body inspection and computer simulation with respect to dimensional tolerance goals.PM/1113
