Hydroxyapatite is a calcium phosphate intensively proposed as bone substitution material because of its resemblance to the constituents minerals present in natural bone. Since hydroxyapatite's properties are mainly adequate for nonload bearing applications, different solutions being tested improving these and upgrading them near target values On other hand, starch (a biodegradable polymer) blends with polymers have been hydroxyapatite mixtures due adhesive, gelling, swelling abilities...
Hydroxyapatite–starch composites solidify rapidly via jellification, making them suitable candidates for robocasting. However, many aspects related to hydroxyapatite powder characteristics, hydroxyapatite–starch interaction, and composition properties need be aligned with robocasting requirements achieve a notable improvement in the functionality of printed scaffolds intended bone regeneration. This article presents preliminary evaluation microcomposites. Thermal analysis starting powders...
Calcium phosphates (CPs) used as biomaterials have been intensively studied in recent years. In most studies, the determination of chemical composition is mandatory. Due to versatility and possibilities performing qualitative quantitative compositional analyses, energy dispersive spectrometry (EDS) a widely technique this regard. The range calcium very diverse, first method approximating type compound being EDS microanalysis, by assessing atomic Ca/P ratio. value ratio can be influenced...
In this paper, silver microparticles were proposed as an additive (wetting agent) in the sintering of bovine bone-derived hydroxyapatite, and their well-known antibacterial properties evaluated for newly-developed materials. Hydroxyapatite was prepared by thermal processing bones, followed milling sorting. After addition, samples tested precursors, green compacts adhered particles-sintered compacts, using complementary morphological, compositional structural evaluation techniques (scanning...
Calcium carbonate from marble and seashells is an eco-friendly, sustainable, largely available bioresource for producing natural bone-like calcium phosphates (CaPs). Based on three main objectives, this research targeted the: (i) adaptation of indirect synthesis route by modulating the amount phosphorus used in chemical reaction, (ii) comprehensive structural, morphological, surface characterization, (iii) biocompatibility assessment synthesized powdered samples. The morphological...
Hydroxyapatite (HA) is one of the most common ceramic materials used for bone substitutions or reconstructions [1]. HA synthesis from natural sources convenient relative to synthetic preparation while ensuring a similarity with viable tissue in terms chemical composition and some other properties. One important markers hydroxyapatite identification differentiation calcium phosphates Ca/P ratio [2]. In order perform proper identification, this should be evaluated high accuracy, which involves...
The aim of the study is to highlight influence cooling conditions on cortical bovine bones derived hydroxyapatite. Bone samples with thicknes 50 mm were cut from central part femur a jigsaw. Then, they processed in order remove all proteins and collagen traces by boiling for 4 hours heating holding them at 450°C 2 hours. They heat treated temperatures ranging 1000° 1300°C, being held 3 then rapidly cooled air atmosphere or ice-water. A natural fracture appeared after applied treatments,...
