Furthermore , the absorbent ' s electroconductibility as the function of its permittivity and permeability was also uncovered . the reflectance of the absorbents was calculated , and the effects of the preparation and the thickness on the absorbing ability were discussed . in a word , the prepared ilmenite absorbents are non - magnetic materials , at given thickness used in applications , the single - layered absorbents have the minimal reflectivity of - 50db and maximal bandwidth of 5ghz 初步研究表明:鈦酸亞鐵類化合物屬于電損耗材料;在實際應用允許的設定厚度范圍內( 2 . 0mm ) ,單層吸收劑的最小反射率( rmin )可達- 50db左右,最大帶寬( ? db )接近5個ghz ,吸波性能很好。

The reduction of ilmenite is one of the key steps of preparation of ti ( c , n ) reinforced iron - based composites by carbothermic reduction . the investigation on the thermodynamics and reaction mechanism of redution has its practical and theoretical value on the stipulation on the process conditions of ti ( c , n ) reinforced iron - based composites 鈦鐵礦的還原過程是碳熱還原制備鐵基ti ( c , n )增強復合材料的關鍵步驟之一,對還原過程的熱力學和反應機理進行研究對制定鐵基ti ( c , n )增強復合材料工藝條件具有重要的現實意義和理論價值。

Three series of absorbent powder samples were synthesized by the high - temperature solid - state method : the first is that fe / ti mol proportion in the material changes regularly ; the other one is that different thuliums doped in the same absorbent ; the last series is the absorbent was doped by different content thulium . the permittivity and permeability of the modified ilmenite absorbents were systematically measured 通過使原料中金屬離子的摩爾比例( fe ti )作有規律變化、在同一基質中摻雜同含量的不同稀土金屬以及改變同種稀土金屬的摻雜量等手段,采用高溫固相合成法制備了不同系列可供進行吸波性能研究的鈦酸亞鐵類化合物吸收劑。

Thermodynamic calculation of the reduction of ilmenite under various temperatures , effects of various reductant on impurities in ilmenite and the reaction mechanism of the reduction of ilmente was calculated and investigated in present work . the reduction sequence of ilmenite was suggested and the effects of impurities on reduction were canalyzed . 本文對不同溫度條件下鈦鐵礦還原過程的熱力學,不同還原劑對鈦鐵礦雜質的影響以及不同溫度條件下鈦鐵礦還原過程的反應機理進行了計算和實驗研究,獲得了鈦鐵礦的還原反應順序,確定了雜質對還原過程的影響。

The ilmenite compound is a sort of inorganic function material , which behaves superior absorbing property in given electroconductibility and can be used as absorbent in stealthy technology , the study about it ' s absorbing property starts not long before . a great variety of possible methods that may synthesis ilmenite compounds had been tried to get a easy and practical way synthesizing studied samples , for example : high - temperature solid - state method ; chemical co - precipitation method ; sol - gel method 鈦酸亞鐵類化合物是一種潛在的具有特征吸波性能的無機功能材料,在特定的電導率范圍內表現優越的吸波性能,可以作為涂層型吸波材料的吸收劑用于隱身技術的研究和應用中,這方面的研制開發在國內外剛剛開始。

4 . three type of basalt is recognized in changle region : a , sapphire - embodied alkli - olivine - basalt of niushan group ( most distributed in fangshan ) , enriched with a large number of mantle - orignated xenoliths with different extent of weathering ; b , alkli - olivine - basalt of niushan group with little sapphire embodied , but contan a few mantle - orignated xenoliths usually samller than that of fangshan , most of the mantle - orignated xenoliths weathered seriously only lefting with some vacant caves , this kind of rock mostly lies in cangshan , taohuashan . and qiaoguan volcanic vent , contain amount of ilmenite ; c , olivine - basalt of yaoshan group , contain neither xenoliths nor sapphire 4 、在昌樂地區區分出三類主要的玄武巖: a ,牛山組含礦的堿性橄欖玄武巖,位于方山,含大量的大小不一的風化蝕變程度不同的地幔巖包體; b ,牛山組幾乎不含礦的堿性橄欖玄武巖,含少量地幔巖包體,且包體一般比方山小,多數已經遭嚴重風化而只留下空洞,含有相當數量的鈦鐵礦,主要位于北巖南部的蒼山,桃花山及喬官火山口。

Ilmenite is an iron titanium ore that earth and the moon have in common . mls - 1a is made from billion - year - old basalt found on the north shore of lake superior and mixed with glass particles that simulate the composition of the lunar soil 鈦鐵礦在地球和月球均普遍存在,而mls - la是仿照月球土壤成份把蘇必略湖北岸數以億年的玄武巖和玻璃顆粒混合而成。

Beneath the relic sand of the outer shelf there is high grade of valuable heavy mineral sand ( for example ilmenite ) reaching the ii anomaly order of marine placers and it is of potential resource prospects 通過碎屑礦物判斷,原巖應是中酸性巖漿巖和淺變質巖類。鈦鐵礦等有用礦物在細砂層位中出現較厚的砂礦異常,顯示一定的淺海砂礦資源潛力。
