Abstract
Glass-ceramics showing a high mechanical strength reinforced by whisker-type wollastonite crystals were prepared by a milling and heat-treatment process using various glass waste and shells as starting materials. In order to blend the starting materials and to accelerate the interaction between the glass and shell during annealing, mechanical milling using a disk-type mill was employed. Formation of whisker-type β-wollastonite crystals was observed in the glass matrix using a X-ray diffraction analysis and a field emission-scanning electron microscope. On increasing the annealing temperature from 800oC and 900oC to 1000oC, the compressive strength of the specimens increased.
