Sintered composite material pressure plate and lateral Spillway containing same

摘要

1. A pressure sintered composite material is provided, including a continuous boron hexagon nitration phase and an unstable material scattered therein, including (a) at least one metal nitride selected from the nitride group of silicon, aluminum or titanium and (b) a stable metal oxide; In the case of metal oxidation, the second substance shall not exceed 35% by weight. It is noted that this material has a high coefficient of thermal expansion and therefore a strong thermal strength. Another chemical property of this kind of material is the low humidity of molten steel,It has a strong chemical resistance to metals. It's a liquid. Finally, it's a material resistant to mechanical wear.
