Eggshell is a solid waste that is available in abundance but is being left unused. Eggshell containing calcium in a high amount. Calcium can be used as a precursor for hydroxyapatite (HAp). Modification of HAp with SiO2 is expected to improve its low mech... see more

Hydroxyapatite (Ca10(PO4)6(OH)2, HAp) is a calcium phosphate-based biomaterial that is widely used in bone implants due to its similarity in composition with the constituent elements of bone. However, HAp still has poor mechanical properties, so research ... see more

A composite of hydroxyapatite modified silica (HASiO2) and 10% (w/w) polyeugenol (PE) was synthesized to produce a calcium phosphate cement with antibacterial activity. The compatibility of the composite (HASiO2_PE) with bone filler requirements was deter... see more

Hydroxyapatite is an inorganic material that is commonly used as a re-mineralizing agent. Adding natural ingredients such as green betel leaf can increase the antibacterial properties due to the presence of phenolic compounds, flavonoids, and tannins. Thi... see more

In this research, the effect of strontium oxide (SrO) and hydroxyapatite (HA) on the properties of mineral trioxide aggregate (MTA) have been studied. MTA contained 20% SiO2, 60% CaO, and 2% Al2O3. Bi2O3 and SrO have been added with 18% (w/w) total percen... see more

Duck eggshell contains very high calcium, making it a raw material for hydroxyapatite (HA) biomedical applications. The aim of this study was to synthesize natural HA from duck eggshell waste using cleaning, drying, smoothing with a smoothness level of pa... see more

The feasibility of soft mechanochemical synthesis was studied here for hydroxyapatite with various types of substitution. It was shown that this method allows obtaining hydroxyapatites substituted with copper or iron cations and hydroxyapatites cosubstitu... see more
