– The aim of this research is to obtain the properties of glass powder that has undergone a high energy milling process. The properties studied include thermal properties, microstructure, and chemical composition. Glass powder has been characterized through XRF and TGA testing, as well as microstructural observations by using SEM. XRF testing is applied to obtain information regarding the chemical composition of glass powder. On the other hand, in order to obtain information regarding the thermal properties of glass powder, TGA is carried out. SEM has been used to examine the microstructure of glass powder. The XRF test results show the dominance of SiO2 as the main element contained in glass powder. SiO2 has a weight percentage of 65.58%. The second dominant element is CaO, which has a weight percentage of 21.34%, MgO 4.34% and Al2O3 2.26%. The uniformity of the particle size of glass powder that has been treated with HEM is shown from the micrographic images as a result of SEM observations. Through SEM observations, data on the distribution of glass powder particle sizes has been also obtained with an average of 41 µm. The measurement results have showed that the smallest particle size has been 10 µm and the largest size has been 80 µm. TGA produces data on the stability of SiO2 purity at a percentage of 85% at a temperature of 950 °C. This suggests that glass powder has good thermal properties, and has a homogeneous and regular microstructure. This information is very useful for developing glass powder materials for brake pad composite applications. © 2024 Praise Worthy Prize S.r.l.-All rights reserved.
