Effects of MgO and Calcining Temperature on the Structure of Aluminum Titanate Synthesized from Industrial Waste
Aluminum titanate has been synthesized by using industrial waste from ferroalloy plant, and titanium white as the main raw materials. The influence of MgO addition and calcining temperature on crystalline structure, micro-morphology and properties of synthesized Aluminum titanate are discussed. The synthesized product was characterized by XRD and SEM, and the crystallinity, cell parameters of crystalline phase are calculated by X' Pert plus software. The experimental result show the crystalline phase Through the research of effect of different concentration of MgO and different of calcining temperature on the crystalline structure of aluminum titanate prepared from industrial waste from ferroalloy plant, the optical concentration of MgO is 1%, and the optical calcining temperature is 1500°C.The grains of main crystalline phase aluminum titanate grow completely with typical orthorhombic feature, the average grain size of No.2 specimen in the micro structures is 10~20um.
