In this study, we use some material to support a crab shell powder to produce ceramic-forming materials such as feldspar, quartz, and kaolin. The samples formed into variations composition and sintering time for 100°C and 900°C for 30 minutes. The calcium concentration of the sample determined by using X-Ray Flouresence (XRF) and molecular bonds obtained from Fourier transform infrared (FTIR) characterization. From the results shows a good sample of further development with ratio composition of the samples are 1.33: 1.33: 0.67: 0.67 at 900°C obtained SiO 2 composition (66.84%), Al 2 O 3 (19.44 %), Fe 2 O 3 (0.63%), CaO (19.44%), K 2 O (0.39%), while CaO has stronger of molecular bonding with each sample, both at sintering time for 100°C and 900°C temperature of sample. This data indicated that crab shell contains high calcium which is component that very effective to use as material of dentures based bioceramic ## Keywords - Bioceramic - Sintering - Materials science - Ceramic - Fourier transform infrared spectroscopy - Mineralogy - Calcium - Quartz - Composite material - Chemistry - Metallurgy - Chemical engineering - Engineering --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
