With blast furnace slag as raw material,the slag fibers were directly prepared by centrifugation process.The crystal content of the slag and properties of the formed slag fibers including the diameter,shot content and moisture with different acidity coefficients （Mk） for the slag,were determined at the same fibrosis temperature.The relationships between Mk and crystal content,the characteristics of slag fibers were established and the influence factors for the quality of slag fibers were also summarized in this paper.The results show that the crystals are mainly composed of calcium akermanite and gehlenite,and with increase in Mk the crystal content of slag gradually decreases,corresponding to changes in fiber properties.The shot content is inhibited by acidity coefficient,and a generally promotive effect on the diameter and moisture content of the slag fibers can be rendered by the crystals.A better fiber quality can be obtained with the value of Mk near 1.3.
