The project aims to enable the inexpensive manufacture of widely used refractories with reduced energy and materials costs and improved thermal and mechanical properties. The project plans to exploit technology patented by the researchers to fabricate percolated mullite materials from fly ash by sintering, yielding properties equivalent or superior to those of fuse-cast alumina-zirconia-silica refractories (AZS). AZS is expensive since it requires melting by fuse-casting and high-purity raw materials. The project aims to eliminate both requirements by sintering and use of waste fly ash, giving microstructures of dense, direct-bonded, percolated, mullite, single crystals, with residual impurities in the interstices that do not affect creep.

该项目旨在以低廉的成本生产广泛使用的耐火材料，降低能源和材料成本，提高热性能和机械性能。该项目计划利用研究人员的专利技术，通过烧结从粉煤灰中制造渗滤莫来石材料，其性能相当于或优于熔铸氧化铝-氧化锆-二氧化硅耐火材料（AZS）。 AZS价格昂贵，因为它需要熔铸熔化和高纯度原材料。该项目旨在通过烧结和使用废粉煤灰来消除这两种要求，获得致密、直接结合、渗滤、莫来石、单晶的微观结构，间隙中残留不影响蠕变的杂质。
