Abstract: 1. A METHOD OF MANUFACTURING SILICON NITRIDE POWDER PRDOMINANTLY IN THE A-PHASE BY REACTING SILICON POWDER WITH A NITRIDING ATMOSPHERE AT AN ELEVATED TEMPERATURE BELOW THE MELTING POINT OF THE SILICON POWDER, WHICH COMPRISES PROVIDING THAT, PRIOR TO NITRIDING, THE SILICON POWDER INCLUDES A COMPOUND WHICH IS IN THE SOLID PHASE AT SAID ELEVATED TEMPERATURE AND WHICH CONTAINS OXYGEN WHICH WILL TAKE PART IN THE NITRIDING REACTION, THE AMOUNT OF SAID COMPOUND BEING SUCH THAT THERE IS PRESENT IN THE SILICON POWDER BETWEEN 1.4% AND 2.5% BY WEIGHT OF REACTABLE OXYGEN.

Abstract: To join a pair of silicon nitride parts, a powdered glass containing silicon, aluminium, an alkaline earth metal and oxygen is provided on at least one of the parts to be joined. The powdered glass is then heated so as to produce molten glass between the parts whereby, on cooling, the glass provides a joint between the parts. The powdered glass can also contain silicon, manganese and oxygen, together with aluminium.
Abstract translation: 为了加入一对氮化硅部件，在要连接的至少一个部件上设置含有硅，铝，碱土金属和氧的粉末状玻璃。 然后将玻璃粉加热，以在部件之间产生熔融玻璃，由此，在冷却时，玻璃提供部件之间的接头。
