PublicationThe important characteristic and properties of dolomite minerals and potential uses as bioceramics: an overview(Trans Tech Publications Ltd, 2025)
;Nur Hasnidah Ahmad Shukeri ; ;Mohamad Hasmaliza ;Dolomite is a raw carbonate mineral rich in contents with calcium, magnesium and oxide compounds also including other minor impurities from other compounds. It could be easily found in sedimentary rock which is most likely known as dolostone associated with limestone and chalk carbonates. This mineral has been used in a variety of industries including agricultural, metallurgy, constructions, biomass and others. Currently, there are abundant sources of local dolomite minerals but have very limited applications when compared to other types of carbonate minerals. This was contributed by the lack of basic technical information on dolomite properties and no extensive research has been done to evaluate the new potential of this mineral. Therefore, this paper made a brief review on the important characteristics, properties and thermal behavior of dolomite and based on these findings discussed the dolomite's suitability and potential to be used as bioceramics and in biomedical applications.< -
PublicationEffect of Ball Milling Process on the Characteristics of Natural Based- And Synthetic Based-Wollastonite for Biomedical ApplicationWollastonite (CaSiO3) is a potential biomaterial, particularly beneficial for biomedical purposes such as tissue bone regeneration. The objective of this study is to evaluate the effect of dry and wet milling conditions on the formation of solid wollastonite bioceramic. In this study, synthetic-type wollastonite was produced from chemically synthetic powder; meanwhile, a combination of seashells and rice husk ash (RHA) was used to form natural-type wollastonite. In sample preparation, CaO and SiO2 powder (1:1 weight ratio) were milled together by planetary ball milling operation under different milling conditions: dry and wet milling. The ball-milled powder mixtures were compacted before sintering at 1200°C for 4 hours. The weight loss and shrinkage of the samples were measured and characterized using XRD, FTIR, and SEM analysis. The results confirmed that the wollastonite phase was formed after the sintering process for both dry and wet ball milled processes with anorthic and monoclinic structure types of calcium silicate phases. The wet-milled processed natural powders relatively formed denser bodies and had a higher weight loss percentage compared to dry-milled processed synthetic powders. In conclusion, wet milling is a more suitable method for producing solid wollastonite via powder sintering. In addition, the natural-based sources from RHA and seashells were able to reach the mineralogical properties comparable to synthetic-based sources for forming wollastonite, which could be promising as an alternative material in biomedical applications.
