Solid-state single crystal conversion (1yr)                                                                       

• Addressed the consolidation and phase stability issues of non-oxide Sr-FAP ceramics.
• Improved the conversion rate with field assisted annealing.
• Correlated grain growth suppression under the electric field to the interface migration.
• Determined impurity ions developed at mobile boundary as the limiting factor of further conversion.

Field-assisted sintering as an efficient consolidation technique (4yrs)

• Fabricated transparent/translucent polycrystalline ceramics, such as Sr-FAP, CaF, Al₂O₃.
• Fulfilled the task of achieving densified BaTiO₃ and zirconia-based composites via spark plasma sintering. 
• Designed and built a field-adjustable furnace for investigating the electric field effect on bulk CuAlO₂ and Sr-FAP ceramics.
