Abstract
This study examines the effects of different burning temperature on the chemical and microstructure properties of WSA. In many parts of the world due to non-availability of proper technology, the farmers generally burn wheat straw after acquiring grains, which causing environmental pollution with fire hazards at farm level and loss valuable commodity. In this research, the influence of different temperature on locally available Wheat Straw in Province KP, Pakistan was study. This research aim to find optimum temperature and burning duration of WSA by examine chemical and microstructural properties of WSA at 550oC for 4 hr, 550oC for 8 hr and 800oC for 30 min. The tests results were categorized through X-ray Diffraction (XRD), X-Ray fluorescence (XRF) and Fourier Transform Infrared Spectroscopy (FTIR). The result showing the 550oC for 4 hr contains high amount of (SiO2+Al2O3+Fe2O3) and amorphous nature as compared to other samples.
Keywords: Wheat Straw Ash (WSA), calcination, optimum temperature, micro-structure properties, amorphous nature
