|Title:||Thermal And Morphological Characterization Of Basalt Continuous Fibers [caracterização Térmica E Morfológica De Fibras Contínuas De Basalto]|
|Abstract:||The basalts are abundant volcanic rocks formed from extensive wastes. The technology of continuous wiring produces basalt filaments in micrometric amorphous long fibers. In this work are presented results of the thermal and morphologic characterization of micrometric basalt fibers. These fibers showed excellent thermal stability, resulting in low weight change (less than 1 wt. %) up to 1000 °C, under heating in inert or oxidant atmosphere. On the other hand, partial crystallization of basalt fibers occurred at ∼ 800 °C, resulting in diffraction peaks in the X-ray patterns, characteristic of silicates and aluminosilicates as the anorthite from the plagioclase class. The morphology of fibers after heating at 1000 °C was changed due to the fusion and crystallization of the present phases.|
