The development of artificial bone using alumina and Nsu clay was carried out in order to determine the effect of Al2O3.2SiO2.2H2O on the properties of locally developed Al2O3-based artificial bone. The raw materials were used to formulate seven samples (A - G) and shaped using casting method. The physical properties investigated after sintering of the samples at 1400oC indicated that samples A-G had linear shrinkage ranging from 3.17% - 3.98% with percentage porosity ranging from 4.78% - 4.51% respectively. The result of bulk density of the samples ranges from 2.6g/cm3 - 4.20g/cm 3 with corresponding compressive strength ranging from 424.5MPa - 489.1MPa. It was discovered that the lower the percentage of alumina content in the composition, the higher the bulk density, linear shrinkage and compressive strength while the lower the porosity of the samples, vice versa. Moreover, sample D of the artificial bone gave the most favourable result in view of the stated properties above. Therefore sample D can be used for production of artificial bone. However, the investigated physical properties gave results that are acceptable for a standard artificial bone, this product is an archetype, therefore, it requires a clinical/medical compatibility test before it can be put to use.
