Study on Characterisation and Property of Local Sand

Glass is an amorphous solid. They are low tensile strength and brittle so that fracture occurs suddenly due to structure, manufacturing process, and properties, without prior plastic deformation. They often fail at a sudden temperature change. The objective is to study on local sand property when exposed to high temperature as well as looking into possibilities of developing a high temperature polymer based on local sand. The microstructure and characteristics of the sample is analyzed by using Scanning Electron Microscope (SEM) and X-Ray Diffraction (XRD). As a conclusion, the sand samples heated at high temperature can be enhanced after running with mechanical ball milling process. This shows that the mechanical milling treatment on the silica sand not only causes size reduction but also structural changes from crystalline phase to distorted structure which are activated due to the high surface energy. From the result, the sand samples were found having better properties after mechanical milling where the samples were found to be more amorphous.
