Fluxing Agent

Stoneware especially tableware is manufactured by mixing the clay, quartz and flux such as feldspar. Thus, the aim of this work is to investigate the possibility of two alternative fluxing agents namely; soda-lime-silica glass (SLS), and borax decahydrate (BD) on characterization, and physico-mechanical properties of stoneware to demonstrate its suitability for tableware production. SLS and BD are incorporated into stoneware at the dosage of 5 %, and 10 % by weight, respectively. The sample was performed by uniaxial pressing (40 MPa) sintered at 1000, 1050, 1100, and 1150°C (2 hours soaking time) to establish minimum sintering temperature. Bulk density, water absorption, and modulus of rupture (MOR) were measured for each sample. Characterization of XRF, XRD, and SEM was carried out and discussed. Results indicated SLS, BD showed higher physico-mechanical properties and vitrified at 1050-1100°C, lower than normal temperature applied for stoneware (1150°C). Consequently, it was determined that the usage of SLS and BD as fluxing agent in stoneware is possible.

Common Opal

Natural opal, an amorphous, hydrous form of silica (SiO2-n-H2O), has been one of the favored precious gemstones for many centuries. Though beautiful, opal is very fragile and is damaged quite easily. Thus, opals of all varieties have been synthesized experimentally and commercially. The objective of this project was to synthesize and to compare crystalline opals. In this work, the development of powder sintered glass ceramics process based on soda lime silica glass waste with metal oxide powder enable jewelry applications. The substantial viscous flow of the glass led to dense products for rapid treatments at relatively low temperatures (900–1,000°C), whereas glass/metal powder interactions resulted in the formation of color agent crystals, provide enhancing optical properties. Several techniques were applied for characterization of the ingots. The chemical analysis was performed by Energy Dispersive X-ray Fluorescence (ED-XRF). The mineralogical compositions of the samples were determined by X-ray diffraction analysis. Raman spectroscopy was applied for optical characterization. The results were compared with a natural common opal. The present investigation demonstrated that the common opal with both color and colorless appearance can be synthesized by the technique, as the crystalline phase of opal structure was identified by XRD measurement. There is a great potential for such materials with novel functionalities for artificial gemstone application, i.e. opal forming.

Work Interaction

Hydroxyapatite (HA) has been widely used in biomedical applications due to its excellent biocompatibility. However, Hydroxyapatite possesses poor mechanical properties and only tolerate limited loads for implants. Titanium is well-known materials applied in implant that has advantage in mechanical properties but poor in biocompatibility. The combination of the Titanium alloy and HA is expected to produce bio-implants with good in term of mechanical properties and biocompatabilty. In this work, interaction and mechanical properties of HA/Ti6Al4V was analyzed. The physical and mechanical properties of HA/Ti6Al4V composite powder obtained from compaction (powder metallurgy) of 60 wt.% Ti6Al4V and 40 wt.% HA and sintering at different temperatures in air were investigated in this study. Interactions of the mixed powders were investigated using X-ray diffraction. The hardness and density of the HA/Ti6Al4V composites were also measured. Based on the results of XRD analysis, the oxidation of Ti began at 700 °C. At 1000 °C, two phases were formed (i.e., TiO2 and CaTiO3). The results showed that the hardness HA/Ti6Al4V composites increased by 221.6% with increasing sintering temperature from 700oC to 1000oC. In contrast, the density of the composites decreased by 1.9% with increasing sintering temperature.
