Research topics from publications: Preparation and properties of Si3N4 ceramics via digital light processing using Si3N4 powder coated with Al2O3-Y2O3 sintering additives; Influence of the content of polymethyl methacrylate on the properties of porous Si3N4 ceramics fabricated by digital light processing; Microstructure and properties of porous Si3N4 ceramics fabricated by digital light processing combined with spark plasma sintering; Influence of the ratio of sintering aids on the properties of porous Si3N4 ceramics fabricated by digital light processing. Representative work: Sintering process is an important factor affecting the properties of porous Si3N4 ceramics. However, there are few studies on the properties of porous Si3N4 ceramics fabricated by combining digital light processing (DLP) technology and spark plasma sintering (SPS) technology. In this study, a method to prepare porous Si3N4 ceramics by combining DLP with SPS technology was proposed, and ceramic samples were successfully prepared. The effect of sintering temperature and holding time of SPS technology on the microstructure and properties of porous Si3N4 ceramics prepared by DLP technology was discussed. With the increase of sintering temperature from 1600 °C to 1700 °C, the conversion content o
