Experimental Investigation of Microstructure and Phase Characterization of Rice Hush Ash (RHA) for Potential Utilization in Metal Matrix Composites
No full textRecent trends in material research and development of composite materials are geared towards reducing cost, recycling and ensuring environmental sustainability. Agricultural waste derivatives have proven to be an alternative or complimentary reinforcement material in the development of metal matrix composites. The current work is an investigation of the microstructure and phase characterization of rice husk ash (RHA) obtained through open air burning. Scanning electron microscopy (SEM) equipped with electron dispersive spectrometry (EDS) was used for the microstructural examination, X – ray fluorescence (XRF) for the mineralogical composition and X – ray diffraction (XRD) for the determination of phases present. Results revealed that RHA is highly siliceous with 93.8% SiO2, highly porous and fibrous material with a wide surface area. EDS profile confirmed the presence of SiO2 and Al2O3. The XRD pattern revealed the presence of quartz, crystabalite and anorthite phases in the RHA. Silica is a hard substance with strong covalent bonds similar to diamond with hardness rating of 7 on Mohs scale and melting point of 1713OC. Thus RHA can be suitable used as a reinforcing material in the development of metal matrix composites for automotive components.

No full textThe purpose of this service is to provide student assistance in submitting and publishing articles in online journals and induction of the Mendeley application. The dedication method uses the Active Participant Participation (PRA) model. Submitting articles in scientific journals generally uses 5 steps to submit (according to the rules of the intended journal and depending on the OJS application used in the journal). After logging in to scientific journals (journals using OJS 2): Click new submission (1), Submit a draft article (Uploading the submission) (2), Fill in the metadata for each Author (Enter Metadata Submission) (3), Upload Supplementary Files namely uploading data related to the contents of the article for revision, generally there are separate instructions from the journal editor (4). Confirming Submission, The inside is the final step and saving your article file can be submitted. Organizing mentoring for submitting articles in online journals, induction of Mendeley applications, and providing expertise that makes it easier for students to write scientific articlesKata Kunci: Jurnal online; Artikel Ilmiah; Aplikasi mendele
