透明镁铝尖晶石纤维及其制备方法
摘要：
本发明涉及提供了一种MgAl2O4透明纤维，其主要特性指标为：晶相组成为MgAl2O4，晶体构造为Fd3m型，晶格常数为0.806～0.808nm，纤维直径在20－1000μm可调，长度在12cm以下可调，折射率为1.718～1.719。本发明还提供制备MgAl2O4透明纤维的方法：采用氧化铝粉、金属铝粉、氧化镁粉、金属镁粉为基质原料，按照50－80％、0－30％、10－20％和0－20％的质量百分比进行配比，混合均匀后在氮气氛炉中烧成，合成透明MgAl2O4纤维。该方法工艺简单，烧成温度较低，降低了成本，易于实现工业化生产。所得产物具有特别优异的光学、介电、物理和机械等综合性能，用途广泛。
摘要（英）：

The invention discloses an MgAl2O4 transparent fiber and preparing method, which is characterized by the following: the crystal phase component is MgAl2O4; the crystal structure is Fd3m type; the constant variance of lattice is 0.806-0.808nm; the fiber diameter is 20-1000 mum, which is adjustable; the length is under 12cm, which is adjustable; the refractivity is 1.718-1.719. The preparing method of MgAl2O4 transparent fiber comprises the following steps: adopting 50-80% alumina powder, 0-30% metal aluminum powder, 10-20% magnesia powder and 0-20% metal magnesium powder as base to allocate; burning in the nitrogen atmosphere after mixing evenly to synthesize the product.
