摘要: 在熱力學分析的基礎上,以高爐渣為原料,引入適當的添加劑,利用碳熱還原-氮化的方法制備了Ca-α-Sialon-SiC粉,得到的Ca-α-Sialon含量最高可以達到81%;利用統計模式識別結合人工神經元網絡優化了工藝.Abstract: Blast furnace slag is a kind of metallurgical solid wastes. In order to make better use of it and enhance its additional value, Ca-α-Sialon-SiC powders were synthesized from blast furnace slag and some additives by carbothermal reduction and nitridition (CRN) based on thermodynamic analysis. The content of Ca-a-Sialon in the sintered samples was up to 81%. The synthesis process of CRN was optimized by Statistical Pattern Recognition (SPR) and Artificial Neural Network (ANN).
