Abstract
Glass-ceramics were fine-grained polycrystalline materials produced by controlled crystallization in the glass phase to have outstanding characteristics. The establishment of basalt from Sukadana - Lampung Province into glass-ceramic begins with the process of reduced size and milled under 200 mesh using an ASTM sieve. The initiated glass-ceramics formation was created by melting the basalt powder at a temperature of 1,250 o C for 2hrs to obtain the glass phase. Glass parent crystallization begins with the stage of nucleation growth. The nucleation process occurs at a temperature 600 o C for 1hr. The crystallization temperature at variations of 850, 950, or 1,050 o C for 3 and 8hrs. The mechanical hardness test result was 637.28 HV1N of the sample with 1,050 o C heating for 3hrs. The highest hardness value is at 837.33 HV1N for a sample of 1,050 o C heating for 8hrs. The hardness value was decreased at samples for 3hrs heating, while it increased for 8hrs of a heating process. All of the heating treatments formed olivine and Anorthite phase but a pyroxene phase was initiated from 950 o C heating process for 3hrs. The use of glass ceramic as an engineering material and biomaterials are promising. It is necessary to continue the development studies on the production process of local basalt resources.
