  1. Mgo and al2o3 can form mgal2o4 existing mainly on the grain boundary through solid phase reaction, which limited the migration of the grain boundary and thereby inhibited the abnormal growth of the alumina grain

    Mgo能與al _ 2o _ 3發生固相應生成主要存在於材料界處的mgal _ 2o _ 4 ,限制了界的遷移,從而抑制了氧化鋁的異
  2. This part emphasizes the synthesis of nanoarrays, aiming at controlling the size and distance of nanocrystallites using calixarene derivatives by altering the size, length and chemical structure of the organic molecules ; 2. this part emphasizes in situ synthesis strategy for fabrication of polymer network of zns based nanopowder, aiming at size controls, coating and preventing agglomeration following " one - pot " synthesis ; this method fits to low cost, large scale production ; 3. according to development in zno nanomaterials, we first report on the synthesis, characterization of amorphous zno, aiming at describing the principles and approaches of synthesis techniques, optical properties, spatial structure and doped effect ; the amorphous zno displays cage - like structure, showing a strong ultraviolet emission while the visible emission is nearly fully quenched, a potential uv - emission material ; 4

    本論文以量子結構自組裝為出發點,提出利用杯芳烴及其衍生物的化學受限應實現尺寸可調半導體納米子自組裝;提出有機聚合網路原位組裝zns基納米熒光粉方法,把熒光粉的納米化、包敷、防團聚在「一鍋」應中完成,適于低成本,批量生產;根據當前zno的研究情況,我們首次合成了非zno ,研究了它的光學性質,確定了它的結構,並對其摻雜進行了初步的研究,非zno表現出強的深紫外發光特性,而可見發射非弱,是一種有巨潛在應用價值的深紫外發光材料;利用非zno的亞穩特性,對化過程中非zno納米zno三維受限量子結構特性,界面特性進行了深入的研究;利用固相熱分解一般受擴散控制特性,實現了尺寸可控的zno三維量子結構的自組裝;利用非zno的高度分散性,容易均勻成膜特性,實現了非誘導低溫液相外延自組裝生高取向zno體薄膜。
  3. The forming - nucleus drive power could form numerous little crystal nucleus under natural melting temperature. the formation of tic particles in the melt could be divided into two phases which was forming - nucleus and growth. the forming mechanism of tic was : melting ti first surrounded c, then ti melting in the alloy and c formed a complicated reaction mesosphere on the carbon surface

    根據熱力學及動力學分析,認為在碳顆界面處tic的形核率很高,形核驅動力足以在正的熔煉溫度下形成眾多的小核;熔體中tic顆的合成可分為形核與兩個階段,其形核機制為:首先活性ti原子包圍c ,溶入合金中的ti與c在碳表面形成一復雜應中間層,隨著應進行, ti和c顆不斷減少,生成的tic不斷彌散分佈於熔體中;其過程伴隨著tic顆的相互堆砌、聚集和形態規則化。
