摘　　要：Basalt fiber(BF)is widely applied in the construction industry to improve the mechanical properties of construction materials.Recent studies show that BF has the potential to further enhance its performance via a crystallization approach.In this work,the glass-ceramic basalt fibers(GCBFs)were prepared through nucleation and crystallization treatments according to the crystallization kinetics calculations.Results from XRD and SEM show that GCBFs have main crystalline phases of Diopside and Augite reach crystallinity of around 46%±10%.In particular,the GCBFs sample with the largest mean crystal size maintains the lowest tensile strength of~197 MPa(compared with the pristine BFs of~737 MPa).Moreover,the weight loss and ion dissolution of GCBFs were explored in seawater environments and it was investigated that,GCBFs have better anti-seawater corrosion than the pristine BFs and have the potential to apply in the marine industry.
