Silicon nitride composite refractories |
摘要 |
The present invention relates to silicon nitride composite refractories having silicon nitride bonds therein and having an increased thermal shock-resistance, an improved molten steel-resistance and an improved mechanical strength, which consists of silicon nitride at 20 to 60 wt %, refractory materials at 10 to 50 wt % and boron nitirde at 1 to 30 wt %, or additionally carbon fibers of 0.5 to 10 wt %. The above described characteristics can be realized because the silicon nitride bonds are bonding structures.
