使用SIALON和SI3 N4氮化硅陶瓷加工高温合金和铸铁具有极大提高生产率的潜力。为了充分利用这种先进陶瓷技术的高金属去除能力，需要日常使用一些常识应用原则。本文对这些应用原则进行了详细介绍。

THE USE OF SIALON AND SI3 N4 SILICON NITRIDE CERAMICS FOR MACHINING HIGH TEMPERATURE ALLOYS AND CAST IRON HAS POTENTIAL FOR ENORMOUS PRODUCTIVITY IMPROVEMENT. TO TAKE FULL ADVANTAGE OF THE HIGH METAL REMOVAL CAPABILITY OF THIS ADVANCED CERAMIC TECHNOLOGY, REQUIRES THE DAY TO DAY USE OF SOME COMMON SENSE APPLICATION PRINCIPLES. THIS PAPER TAKES A NUTS AND BOLTS APPROACH TO THESE APPLICATION PRINCIPLES.
