Symposium Additive Manufacturing of Ceramic-based Materials: Process Development, Materials, Process Optimization and Applications
Presentation Title Irradiative Ceramization of Chemically Bound Phosphate Ceramics (CBPCs) to Enable Direct Additive Manufacturing of Ceramic Composites
Author(s) Mark D. Losego
On-Site Speaker (Planned) Mark D. Losego
Abstract Scope This talk will introduce a rapid, pressureless process to chemically bind ceramic parts via a combination of inorganic phosphate chemistries and electromagnetic irradiation. The ceramic components are synthesized from slurries of ceramic powders and Al(H2PO4)3 binders. In initial studies, short-waved IR irradiation drives phosphate condensation reactions, however under these low irradiation powers (~0.2 W/cm2), condensation and ceramization requires minutes to tens of minutes to complete. Using a high-power flash lamp annealing (FLA) system (~10 kW/cm2) enables rapid ceramization in under 1 min and denser overall microstructures. Interestingly, though, the total irradiation energy required to drive complete ceramization is similar for both processes. The talk will also discuss the importance of light absorbers and the development of printed, high-temperature thermochromic ceramic sensors using this new additive manufacturing approach.
