Luminescent and scintillation ceramic materials with complex shapes, which can be created by stereolithography 3D printing, are of interest for special phosphor detector applications. Starting powders such ceramics may possess UV absorption bands; therefore, it is important to study the possible influence powders’ luminescent properties on printing process. This paper deals garnet oxides, Y3Al5O12 Gd3Al2Ga3O12—well-known hosts materials. The photopolymerization rates slurries based produced...
Dense and transparent ceramic samples of a (Gd,Y)3Al2Ga3O12:Ce scintillator were obtained by using stereolithography-based Digital Light Processing (DLP) 3D printing for compacting, subsequent burnout, pressureless sintering. The effects stoichiometric deviations green body compaction methods (uniaxial pressing versus DLP printing) on the optical, luminescent, scintillation properties ceramics analyzed. An excess Y Gd in composition led to an increase transmittance acceleration kinetics....
The production of the scintillation ceramics can require utilization phosphorus compounds at certain stages 3D-printing, such as vat polymerization, applied for formation green bodies before sintering. effect additive on microstructure, optical, and parameters Gd1.494Y1.494 Ce0.012Al2Ga3O12 (GYAGG:Ce) obtained by pressureless sintering 1650 °C in an oxygen atmosphere was investigated first time. Phosphorus introduced form NH4H2PO4 into initial hydroxocarbonate precipitate a wide...
A comprehensive study of the influence nature aliphatic monomers ethylene glycol diacrylates on properties photo-cured suspensions based a complex oxide powder with garnet structure (Gd,Y)3Al2Ga3O12:Ce composition for three-dimensional printing by Digital Light Processing (DLP) has been carried out. The rheological characteristics suspensions, as well polymerization depth, were studied using both model HDDA monomer and specified diacrylates, when filled solid particles 30 vol.% (70 wt.%)....
Phosphoric acid ester, a typical component of commercial dispersants, affects the functional properties Gd1.494Y1.494Ce0.012Al2Ga3O12 ceramics. In sintered ceramics, residual phosphorus can reach up to 40–70% introduced amount. The admixture located on surfaces particles activates grain growth during sintering and leads formation secondary phases rare-earth phosphates. With increasing concentration, density optical transmittance ceramics decrease. Relatively small amount improve luminescence...
The rheological characteristics of systems based on stabilized zirconium dioxide containing previously unused dispersing additives from BYK-Chemie, GmbH, have been studied to obtain photo-cured suspensions with properties that allow 3D-printing ceramic samples complex shape by stereolithography. suitability the compositions has demonstrated prototypes thin-walled crucibles for thermal analysis. Ill. 4. Ref. 21. Tab. 2.
The influence of the structure and properties acrylate monomers on rheology polymerization suspensions containing partially stabilized zirconium dioxide, a dispersant photoinitiator as ceramic filler is investigated. It has been shown that use DISPERBYK 2013 additive makes it possible to obtain 1,6-hexanediol diacrylate, dipropylene glycol diacrylate tripropylene with viscosity value below 5 Pa?s at high (up 41 vol. %) filling TZ-3YS-E powder. possibility using obtained for three-dimensional...
