In this thesis there were two main purposes, the first one being to investigate effects of zinc borate (ZB) on the flammability behavior of ABS when used with and without a traditional brominated flame retardant (BFR) / antimony trioxide (AO) system. The second purpose was to investigate contribution of nanoclays (NC) to the flame retardancy performance of the same traditional BFR compound with various combinations of AO and ZB again in ABS matrix. For these purposes, materials were melt compounded by using...

Epoxy (EP) is a thermosetting polymer which has high dimensional stability. However, the brittleness, low resistance to impact failure and flammability are some limitations of the epoxy polymer. These properties limit the usage of epoxy in the applications where high mechanical strength and flame retardancy properties are needed. The purposes of this study are to improve both mechanical and flame retardancy properties of epoxy by the addition of boron containing compounds (BCC) mainly boron carbide (B4C), a...
Investigation of neutron sensitivity of un-doped and Dy-doped CaB4O7 for thermoluminescence applications
Iflazoglu, Sera; Yılmaz, Ayşen; KAFADAR, VURAL EMİR; YAZICI, AHMET NECMEDDİN (2018-09-01)
In this study, thermoluminescence characteristics of un-doped and Dy-doped calcium tetraborate (CaB4O7) compounds are reported. The polycrystalline powder samples of un-doped and Dy-doped CaB4O7 were prepared by a solid-state reaction at high-temperature method. The identification and characteristics of the obtained compounds were determined by X-ray diffraction, Fourier transform infrared analysis, differential thermal analysis, thermogravimetric analysis, and scanning electron microscopy. The glow curves ...
