Kesan nisbah mol CaO/P2O5 ke atas penghabluran kaca kalsium fosfat

Kesan nisbah mol CaO/PzOs ke atas penghabluran kaca kalsium fosfat merupakan suatu kajian awal ke atas sistem kaca berkenaan. Sistem kaca ini menjadi semakin penting dan menarik untuk dikaji berikutan keupayaannya bertindak sebagai bahan bioseramik. Kajian telah dimulakan dengan kerja-kerja pengh...

Metallurgy Kesan nisbah mol CaO/PzOs ke atas penghabluran kaca kalsium fosfat merupakan suatu kajian awal ke atas sistem kaca berkenaan. Sistem kaca ini menjadi semakin penting dan menarik untuk dikaji berikutan keupayaannya bertindak sebagai bahan bioseramik. Kajian telah dimulakan dengan kerja-kerja penghasilan kaca kalsium fosfat dengan empat komposisi teori nisbah mol Ca0/P20 5 iaitu 0.85, 0.95, 1.10 dan 1.20. Hasil peleburan kemudiannya dianalisis menggunakan analisis pembelauan sinar-X (XRD), analisis pendafluor sinar-X (XRF) dan analisis terma pembezaan (DTA). Seterusnya, seramik kaca kalsium fosfat dihasilkan melalui proses olahan haba pada suhu 600°C. Dua tempoh olahan haba telah digunakan iaitu 24 jam dan 48 jam. Sementara itu, dua kadar kenaikan suhu (1 0°C/min dan 2°C/min) semasa olahan haba turut diselidiki kesannya ke atas penghabluran kaca kalsium fosfat. The effect of the CaO to P205 mole ratio on the crystallisation of Calcium phosphate glass is the first study based on the Ca0/P205 glass system. The investigation on this system is of interest due to its capability to be used as a bioceramic material. In the first stage of the research, phosphate glasses with theoretical composition of 0.85, 0.95, 1.10 and 1.20 mol ratios were produced. Then, they were analysed using X-ray diffraction (XRD), X-ray fluorescent (XRF) and differential thermal analyses (DTA). Next, they were heat-treated at 600°C for 24 hours and 48 hours to produce calcium phosphate glass ceramic. The effects of two different rates of temperature increase on the crystallisation of calcium phosphate glass were investigated during this process. 2000-10 Thesis http://eprints.usm.my/35501/ http://eprints.usm.my/35501/1/JARIAH_BT_MOHAMAD_JUOI_%28KHK%29_%28NN24%29.pdf application/pdf en public masters Universiti Sains Malaysia Pusat Pengajian Kejuruteraan Bahan & Sumber Mineral (School of Material & Mineral Resource Engineering)
