可应用于燃气轮机燃烧室的刚玉-莫来石烧成砖及制备方法
摘要：
本发明涉及一种用于燃气轮机燃烧室的耐火材料，公开了一种刚玉-莫来石烧成砖，至少由以下原料经高温烧结后得到，所述原料的质量百分比为30-40％的刚玉颗粒、35-45％的莫来石颗粒、余量为刚玉细粉和微粉，其中，细粉和微粉具有相对颗粒更小的粒度，此外还公开了一种用于烧制上述刚玉-莫来石烧成砖的方法以及应用上述方法得到的刚玉-莫来石烧成砖。本发明的优点在于，得到的烧成砖具有较高的强度，性质稳定，体积稳定性高，能够满足内燃机燃烧室内的高强度，高耐火度，耐热耐震，耐腐蚀以及耐冲刷的要求，具有较长的使用寿命。
摘要（英）：

The invention relates to a refractory material for a gas turbine combustion chamber and discloses a corundum-mullite burnt brick. The corundum-mullite burnt brick is mainly obtained by high-temperature sintering of the following raw materials by mass percent at least: 30-40% of corundum particles, 35-45% of mullite particles and the balance of corundum fine powder and micro powder, wherein the fine powder and the micro powder have smaller granularity than the particles. Besides, the invention also discloses a method for sintering the corundum-mullite burnt brick and a corundum-mullite burnt brick obtained by application of the method. The obtained burnt brick is relatively high in strength, stable in performance and high in volume stability, the requirements for high strength and refractoriness, heat and shock resistance, corrosion resistance and scouring resistance in the gas turbine combustion chamber can be met and a relatively long service life is achieved.
