Initial Sintering Mechanism of Mesocarbon Microbeads

The document analyzes the initial sintering mechanisms of mesocarbon microbeads through various experiments. It finds that sample shrinkage is primarily due to increasing theoretical density caused by crystallographic transformation during heating. The β-resin helps maintain particle cohesion during sintering. Sample porosity remains largely unaffected by the sintering process. Thermogravimetric analysis and heating schedule experiments help understand mass change and shrinkage over time and temperature.
