UV-Curable Polyborosilazane Precursors for SiBCN Coatings under Harsh Environments

“…6 As the entire process of PDCs incorporates organic and inorganic stages, some organic advantages can be utilized throughout the process of preparing complex-shaped ceramics, such as continuous fibers, 3D complex structures, and composites 7,8 to achieve various functions and applications. 9,10 The process of producing ceramics using PDCs typically involves four steps: synthesis, shaping, curing, and pyrolysis. Additionally, chemically produced organic precursors usually have a specific glass transition temperature, allowing for easy shaping into a variety of forms.…”

As the entire process of PDCs incorporates organic and inorganic stages, some organic advantages can be utilized throughout the process of preparing complex-shaped ceramics, such as continuous fibers, 3D complex structures, and composites , to achieve various functions and applications. , …”

Additive Manufacturing of SiOC, SiC, and Si3N4 Ceramic 3D Microstructures

“…Silicon ceramics and their suspensions possess distinctive features that make them suitable for a range of applications where hard and lightweight materials are necessary. [13][14][15][16] However, the combination of conventional blends of organic resin and commercial ceramic powder has limitations that require attention. Suspensions of inorganic particles and organic resists often have limited resolution, which can lead to poor quality of the resulting inorganic structures.…”
