摘要：

The paper examines how mechanical activation influences the in-situ phase formation of aluminosilicates in the BN-Al2O3-SiO2-Si3N4 system. The major factor that influences the activation of the charge is the duration of high-energy machining. Results from infrared spectroscopy and data on the particle size and specific surface of the charge show that short-term (10-20 min) attritor grinding is sufficient to obtain a mixture and composite of high quality.
