In this work, we adopt a combination of low molecular weight PEG (L-PEG) and high molecular weight PEG (H-PEG) as water-soluble binder to fabricate injection-moulded ceramic parts with large section. The mechanism of the combination of PEGs removal was proposed for the first time. Defect-free near gear parts with large-sized-section (thickness – 16 mm) were successfully fabricated through water extraction (15 h) followed by rapid thermal pyrolysis (4.5 h). It solves the difficulty of fabricating injection-moulded ceramic parts with large section and our approach is energy saving and high-efficiency as compared with conventional thermal debinding. The results demonstrate that our approach of partially water-debinding followed by rapid thermal pyrolysis could solve the problems of conventional thermal debinding, providing an effective route for the production of injection moulded ceramic parts with large section.
