蓝晶石是一种高铝硅酸盐矿物,具有很高的耐火度和特殊的高温热膨胀性能,而且又有抗磨、抗腐蚀和机械强度高等特性,因此已成为一种新型矿物原料用于冶金、陶瓷、宇航等方面。蓝晶石作为一种特征的变质矿物,在江苏省东北部变质岩发育的地区,有着有利的成矿地质条件和找矿前提。五年多来,已发 Kyanite is a high-aluminosilicate mineral with high refractoriness and exceptional high-temperature thermal expansion properties and is also a new mineral material for anti-wear, corrosion and high mechanical strength Metallurgy, ceramics, aerospace and so on. As a characteristic metamorphic mineral, kyanite has favorable geological conditions and prospecting conditions in the developed area of ​​metamorphic rocks in the northeast of Jiangsu Province. For more than five years, it has been sent
