摘要：
Provided is a method for manufacturing a sintered body of an alumina- spinel composite powder for bulletproof material, in which alumina (AI2O3) and magnesium oxide (MgO) raw materials are milled into an alumina powder and a spinel composition powder through high-energy milling, and thereafter heat- treating, mixing and sintering are sequentially performed. Since the method employs high-energy milling, it is possible to synthesize spinel phase through heat-treatment at a low temperature for a short duration. Furthermore, the small amount of additive is added during the sintering process so that it is possible to obtain a sintered body of a composite powder with a low density and a high densification degree at a low temperature.
摘要（中）：
本发明提供一种用于防弹材料的氧化铝 - 尖晶石复合粉末的烧结体的制造方法，其中将氧化铝（Al 2 O 3）和氧化镁（MgO）原料通过高能量研磨粉碎成氧化铝粉末和尖晶石组合物粉末 ，然后依次进行热处理，混合和烧结。 由于该方法采用高能量研磨，所以可以通过在低温下进行短时间的热处理来合成尖晶石相。 此外，在烧结过程中添加少量的添加剂，从而可以在低温下获得密度低，致密化程度高的复合粉末的烧结体。
