Method for preparing aluminum titanate-anorthite heat storage ceramic from ferrotitanium slag
The invention discloses a method for preparing aluminum titanate-anorthite heat storage ceramic by using ferrotitanium slag, which comprises the following steps: respectively calcining raw materials including ferrotitanium slag, MgO, TiO2 and SiO2 to remove impurities, and then sequentially carrying out ball milling and mixing, adding polyvinyl alcohol for granulation, aging, dry pressing and sintering to obtain the aluminum titanate-anorthite heat storage ceramic. The method is simple in technological process, high in titanium iron slag utilization rate, high in economic benefit and low in cost, and the finally obtained aluminum titanate-anorthite heat storage ceramic has the advantages of being high in heat storage capacity, good in thermal shock resistance and the like.
本发明公开了一种利用钛铁渣制备钛酸铝‑钙长石储热陶瓷的方法，该方法是将钛铁渣、MgO、TiO2和SiO2在内的原料分别煅烧除杂后再依次进行球磨混料、加入聚乙烯醇造粒、陈腐、干压成型和烧结，即得。该方法工艺流程简单，钛铁渣利用率高，经济效益高，成本低，最终得到的钛酸铝‑钙长石储热陶瓷具有储热能力强和抗热震性好等优点。
