Production of silica fume-based geopolymeric foam
Shakouri, Sahra; Erdoğan, Sinan Turhan; Department of Civil Engineering (2017)
This study investigates the activation of silica fume powder with sodium hydroxide solutions, to produce foamy geopolymeric material. The powder was mixed with NaOH solutions of different concentration, at different solution-to-powder ratios and cured at 100 °C for different length of time. Upon to heating to 200-500 °C, a volume expansion up to 10 times of the initial paste volume took palace, and a porous structure resulted. Ground perlite, expanded perlite and basalt fibers were tested as additives to th...
Production of Potassium Titanate Whisker Reinforced Dental Composites
Kapusuz, Derya; Park, Jongee; Öztürk, Abdullah (2013-01-01)
Potassium titanate (K2O.nTiO2) whiskers (KTWs) were produced by sol-gel method and embedded into UDMA-TEGDMA resins to produce KTW reinforced composites that could be used for both anterior and posterior fillings. The effect Ti/K molar ratio on the chemical, structural and functional properties of the KTWs was investigated using XRD, HR-TEM, and BET analysis. Morphology and the surface properties of the KTWs rely on the Ti/K ratio. However, HR-TEM studies clarified that the KTWs grow along [110] axis regard...

Production of flame retardant polyester composites and fibers
Akan, Mithat; Bayramlı, Erdal; Bayram, Göknur; Department of Polymer Science and Technology (2013)
Poly(ethylene terephthalate) (PET) fiber is one of the leading synthetic fibers in textile industry. However, its flame retardant properties are poor to be used in certain applications, therefore flame retardant additives are generally used in order to improve flame retardant properties of PET. The main objective of this study is to find suitable flame retardant additives for PET that can synergize with each other and that can improve the flame retardant properties without compromising the mechanical proper...
