This research aimed to investigate the possibility of utilization basalt fibers as a raw material for ceramic production. Both quartz and feldspar were replaced partially or entirely by basalt fiber in the range of 10 -25 wt. %. The mixture of ceramic powders and basalt fibers were uniaxially pressed and sintered at temperatures between 1000 and 1200°C for 1 h. The substitution of basalt fibers in ceramic compositions demonstrated the positive effect on the physical and mechanical properties.

The highest density and strength were 2.40 g•cm -3 and 116 MPa, respectively, when replacing feldspar and quartz with basalt up to 20 wt. % (CB-20) and sintering at 1150°C.
