Results:Improving crystallization temperature can increase the grain sizes and aspect ratio of mica and improve the three-point bending strength and fracture toughness of the glass-ceramics. Vickers hardness and the index of brittleness decrease with increasing of temperature.
结果：随着晶化温度的逐步升高，四硅氟云母的晶粒大小和径厚比逐步增大，抗弯强度和断裂韧性亦逐渐增高，维氏硬度和脆性指数随温度升高而降低。
