以煤矸石和碳黑为主要原料,在1800 K下碳热还原氮化合成了纯度较高、含有大量晶须的β-SiAlON材料.FESEM照片表明β-SiAlON晶须多为细长柱状,直径120～220 nm,长度1.5～5 μm,晶须生长机制由VLS(vapor-liquid-solid)机制和VS(vapor-solid)机制组成.

이매안석화탄흑위주요원료,재1800 K하탄열환원담화합성료순도교고、함유대량정수적β-SiAlON재료.FESEM조편표명β-SiAlON정수다위세장주상,직경120～220 nm,장도1.5～5 μm,정수생장궤제유VLS(vapor-liquid-solid)궤제화VS(vapor-solid)궤제조성.
β-SiAlON with a lot of slender cylindrical whiskers, has been synthesized by carbonthermal reduction-nitridation method form Coal gangue and carbon black at 1800 K. FESEM photographs showed that diameter of β-SiAlON whisker is 120-220 nm and length in the majority is about 1.5-5 μm. The VLS (vapor-liquid-solid) and VS (vapor-solid) mechanisms have been adopted to explain the behavior of whiskers growth.
