Abstract

Durability of materials to flame and stability at high temperatures are very important in order to increase the field of use. Non-flammability is not the only requirement materials should not have toxic gas products during the burning, also. Anhydrous zinc borate was chosen as flame retardant due to its advantages, such as; light weight, high melting point, low thermal expansion, and intrinsic smoke suppressant and corrosion resistance properties. For the synthesis, metallic zinc and anhydrous boron oxide powders were mixed in the attritor working at 600 rpm. Powder product was sintered at atmospheric conditions according to the phase change temperature determined by TGA-DSC analyses. Synthesized zinc borate was grinned up to nanometer size by Spex type grinder. Zinc borate was doped in binder to decrease the flammability. The properties of the produced materials were determined and compared by LOI, TGA-DSC, SEM and oven according to the zinc borate ingredients.
