【摘要】 本文回顾了目前工业粉煤灰的资源综合利用与再循环技术,提出拟利用电厂粉煤灰,合成具有环境友好功能的新型生态赛隆耐火材料/陶瓷新思路。研究结果表明,通过酸洗工艺参数的控制,可实现粉煤灰中杂质铁的去除,有利于合成材料的体积密度的改善。采用胶态成型工艺与碳热还原氮化工艺,可实现与环境友好的生态环境材料的研制。更多还原

【Abstract】 After review of recycling and reuse of industrial fly-ash at present, the novel route for obtaining high value green Sialon ceramic composite/refractory using fly-ash from dynamoelectric factory was put forward in the paper. The results indicate that the removal of iron element in fly-ash controlled by acid-wash purifying process was available for improvement in bulk density of as-fabricated refractories. The low-cost, high-performance and friendly-environmental ecological materials can be attained while both the colloidal process and carbothermal reduction nitridation (CRN) were used.更多还原
