中文摘要：

高钛炉渣的微波吸收性质被使用微波洞不安技术调查。包含超过 90% TiO ₂ 的高钛炉渣被钛铁矿的 carbothermal 减小准备。在加热过程的微波的高钛炉渣的温度上升曲线被获得。在微波照耀前后的高钛炉渣的水晶的混合物被 X 光检查 diffractometry (XRD ) 获得并且描绘。高钛炉渣的粒子尺寸和高钛的混合物的效果与 V ₂ 吸收性质的微波上的 O ₅ 系统地被调查。结果证明高钛炉渣有好微波吸收性质；未经治疗的高钛炉渣主要由锐钛矿和铁钛氧化物的水晶的混合物组成，当对待的主要是的微波照耀金红石和铁钛氧化物的水晶的混合物创作了时。合成锐钛矿在微波照耀下面为 20 min 在大约 1 050 ° C 完全被转变成金红石。高频率移动和电压的低振幅使高钛炉渣成为理想的微波吸收剂。粒子尺寸和 V ₂ O ₅ 被发现是为微波吸收的最佳条件。

英文摘要：

Microwave absorbing properties of high titanium slag were investigated by using microwave cavity perturbation technique. High titanium slag containing more than 90% TiO2 was prepared by carbothermal reduction of ilmenite. The temperature rise curve of high titanium slag in microwave heating process was obtained. Crystalline compounds of high titanium slag before and after microwave irradiation were obtained and characterized by X-ray diffractometry （XRD）. Effects of particle size of high titanium slag anal mixtures of high titanium slag with different mass fractions of V2o5 on microwave absorbing properties were investigated systematically. The results show that high titanium slag has good microwave absorption property; untreated high titanium slag mainly consists of crystalline compounds of anatase and iron titanium oxide, while the microwave-irradiation treated one is mainly composed of crystalline compounds of rutile and irgn titanium oxide. Synthetic anatase is transformed completely into rutile at about 1 050 ℃ for 20 min under microwave irradiation. High frequency shift and low amplitude of voltage make high titanium slag an ideal microwave absorbent. 180 μm of particle size and 10% mass fraction of V2O5 are found to be the optimum conditions for microwave absorption.
