| 2 | Photopolymerization-based additive manufacturing of ceramics:A systematic review显示文摘Conversion of inorganic-organic frameworks (ceramic precursors and ceramic-polymer mixtures) into solid mass ceramic structures based on photopolymerization process is currently receiving plentiful attention in the field of additive manufacturing (3D printing).Various techniques(e.g.,stereolithography,digital light processing,and two-photon polymerization) that are compatible with this strategy have so far been widely investigated.This is due to their cost-viability,flexibility,and ability to design and manufacture complex geometric structures.Different platforms related to these techniques have been developed too,in order to meet up with modem technology demand.Most relevant to this review are the challenges faced by the researchers in using these 3D printing techniques for the fabrication of ceramic structures.These challenges often range from shape shrinkage,mass loss,poor densification,cracking,weak mechanical performance to undesirable surface roughness of the final ceramic structures.This is due to the brittle nature of ceramic materials.Based on the summary and discussion on the current progress of material-technique correlation available,here we show the significance of material composition and printing processes in addressing these challenges.The use of appropriate solid loading,solvent,and preceramic polymers in forming slurries is suggested as steps in the right direction.Techniques are indicated as another factor playing vital roles and their selection and development are suggested as plausible ways to remove these barriers. | Sefiu Abolaji RASAKI Dingyu XIONG Shufeng XIONG Fang SU Muhammad IDREES Zhangwei CHEN | 2021 | Journal of Advanced Ceramics2021，10，3： | 8 |

| 4 | High performance hydroxyapatite ceramics and a triply periodic minimum surface structure fabricated by digital light processing 3D printing显示文摘High performance hydroxyapatite(HA)ceramics with excellent densification and mechanical properties were successfully fabricated by digital light processing(DLP)three-dimensional(3D)printing technology.It was found that the sintering atmosphere of wet C02 can dramatically improve the densification process and thus lead to better mechanical properties.HA ceramics with a relative density of 97.12%and a three-point bending strength of 92.4 MPa can be achieved at a sintering temperature of 1300℃,which makes a solid foundation for application in bone engineering.Furthermore,a relatively high compressive strength of 4.09 MPa can be also achieved for a DLP-printed p-cell triply periodic minimum surface(TPMS)structure with a porosity of 74%,which meets the requirement of cancellous bone substitutes.A further cell proliferation test demonstrated that the sintering atmosphere of wet CO2 led to improve cell vitality after 7 days of cell culture Moreover,with the possible benefit from the bio-inspired structure,the 3D-printed TPMS structure significantly improved the cell vitality,which is crucial for early osteogenesis and osteointegration. | Yongxia YAO Wei QIN Bohang XING Na SHA Ting JIAO Zhe ZHAO | 2021 | Journal of Advanced Ceramics2021，10，1： | 5 |
| 5 | Influence of Al_(2)0_(3) content on mechanical properties of silica-based ceramic cores prepared by stereolithography显示文摘Silica ceramic cores have played an important part in the manufacture of hollow blades due to their excellent chemical stability and moderate high-temperature mechanical properties.In this study,silica-based ceramics were prepared with Al_(2)0_(3) addition by stereolithography,and the influence of Al_(2)0_(3) content on mechanical properties of the silica-based ceramics was investigated.The Al_(2)0_(3) in silica-based ceramics can improve the mechanical properties by playing a role as a seed for the crystallization of fused silica into cristobalite.As a result,with the increase of Al_(2)0_(3) content,the linear shrinkage of the silica-based ceramics first decreased and then increased,while the room-temperature flexural strength and the high-temperature flexural strength first increased and then decreased.As the Al_(2)0_(3) content increased to 1.0 vol%,the linear shrinkage was reduced to 1.64%because of the blocked viscous flow caused by Al_(2)0_(3).Meanwhile,the room-temperature flexural strength and the high-temperature flexural strength were improved to 20.38 and 21.43 MPa with 1.0 vol%Al_(2)0_(3),respectively,due to the increased a-cristobalite and P-cristobalite content.Therefore,using the optimal content of Al_(2)0_(3) in silica-based ceramics can provide excellent mechanical properties,which are suitable for the application of ceramic cores in the manufacturing of hollow blades. | Wen ZHENG Jia-Min WU Shuang CHEN Chang-Shun WANG Chun-Lei LIU Shuai-Bin HUA Kang-Bo YU Jie ZHANG Jing-Xian ZHANG Yu-Sheng SHI | 2021 | Journal of Advanced Ceramics2021，10，6： | 4 |

| 7 | Micro-fabrication of ceramics:Additive manufacturing and conventional technologies显示文摘Ceramic materials are increasingly used in micro-electro-mechanical systems(MEMS)as they offer many advantages such as high-temperature resistance,high wear resistance,low density,and favourable mechanical and chemical properties at elevated temperature.However,with the emerging of additive manufacturing,the use of ceramics for functional and structural MEMS raises new opportunities and challenges.This paper provides an extensive review of the manufacturing processes used for ceramic-based MEMS,including additive and conventional manufacturing technologies.The review covers the micro-fabrication techniques of ceramics with the focus on their operating principles,main features,and processed materials.Challenges that need to be addressed in applying additive technologies in MEMS include ceramic printing on wafers,post-processing at the micro-level,resolution,and quality control.The paper also sheds light on the new possibilities of ceramic additive micro-fabrication and their potential applications,which indicates a promising future. | Hany HASSANIN Khamis ESSA Amr ELSHAER Mohamed IMBABY Heba H.EL-MONGY Tamer A.EL-SAYED | 2021 | Journal of Advanced Ceramics2021，10，1： | 1 |
| 8 | Preparation and properties of T-ZnO_(w) enhanced BCP scaffolds with double-layer structure by digital light processing显示文摘Bone scaffolds require both good bioactivity and mechanical properties to keep shape and promote bone repair.In this work,T-ZnO_(w) enhanced biphasic calcium phosphate(BCP)scaffolds with triply periodic minimal surface(TPMS)-based double-layer porous structure were fabricated by digital light processing(DLP)with high precision.Property of suspension was first discussed to obtain better printing quality.After sintering,T-ZnO_(w) reacts with b-tricalcium phosphate(β-TCP)to form Ca_(19)Zn_(2)(PO_(4))14,and inhibits the phase transition toα-TCP.With the content of T-ZnO_(w) increasing from 0 to 2 wt%,the flexural strength increases from 40.9 to 68.5 MPa because the four-needle whiskers can disperse stress,and have the effect of pulling out as well as fracture toughening.However,excessive whiskers will reduce the cure depth,and cause more printing defects,thus reducing the mechanical strength.Besides,T-ZnO_(w) accelerates the deposition of apatite,and the sample with 2 wt%T-ZnO_(w) shows the fastest mineralization rate.The good biocompatibility has been proved by cell proliferation test.Results confirmed that doping T-ZnO_(w) can improve the mechanical strength of BCP scaffolds,and keep good biological property,which provides a new strategy for better bone repair. | Ming-Zhu PAN Shuai-Bin HUA Jia-Min WU Xi YUAN Ze-Lin DENG Jun XIAO Yu-Sheng SHI | 2022 | Journal of Advanced Ceramics2022，11，4： | 1 |
