https://doi.org/10.17073/1683-4518-2014-5-41-45
Abstract
A new technology for preparation of corundum-mullite refractories was proposed. The crystal structures of raw materials before and after sintering process were characterized using XRD. The analysis results indicated that corundum and mullite were mainly crystalline compounds in the sintering samples. The optimum conditions result of microwave absorbing properties in prepared corundum-mullite refractories with particle size of 75 pm. Ill. 5. Ref. 10. Tab. 1.
