Material characteristics such as grain growth, shrinkage, and pore evolution may exhibit different phenomena for micron or sub-micron feature sintering compared to bulk sample sintering, due to its small size. In this study, nanoparticle-based micron and submicron pillars are created with TiO2 nanoparticle suspension via a template-assisted method. Grain growth, porosity, and shrinkage of sintered samples are studied from 450°C to 650°C for 1 hour and 24 hours. The effects of solids loading (from 15 vol% to 35 vol%) and agglomeration level (controlled by adding 10 wt% and 20 wt% ethanol in TiO2 nanoparticle suspensions) for different feature arrays are also investigated. The fundamental understanding of small feature sintering is discussed.
