Examples
- The microstructure of the products sintered at 1100 c ~ 1300 c were discussed by sem coupled with eds . combined with xrd patterns , the products sintered at 1200 c have the finest crystals and the densest fabric
结合xrd图谱， 1200温度下的烧结产物晶体发育最好，且结构最致密，研究了该温度下掺加7vol . %和1svo - It was confirmed that the first reaction layer of tic with very fine crystal grains is due to the reaction ti + sic - tic + si . this reaction is a reaction - controlled one . however , the other reactions in the second step a re controlled by elements diffusion
Scs一6sic / ti3ai复合材料的界面反应产物可多达6层，依次为:紧挨着纤维的晶粒细小的tic层、晶粒细小的tissi ;层、等轴晶粒的tic层、 ti3si层、 ti3aic层及ti5si3层。 - The powder synthesized by co - precipitation has many advantages such as fine crystal grains , good homogeneity and purity , high activity , and these favor the solid phase reaction . so the magnetic properties of the samples were better than that of those prepared by conventional oxides methods
共沉淀法制备的粉料具有晶粒细小，均匀性好，活性高，纯度高等特点，这些特点有利于固相反应，能够得到性能优良的铁氧体材料。 - The influence of nano - al2o3 on the sintering and the properties of the si3n4 ceramics was researched in this paper . the samples with different amount of nano - al2o3 were obtained by using pressureless sintering at 1600 , 1650 , 1700 in the nitrogen atmosphere . the microstructure and the composition of the ceramics were determined by the means of x - ray , sem , micro - hardness meter etc . it is show that the sisty ceramics can be densified at 1650c to % percent of the theory density through the addition of nano - al2o3 ( the value could be 90 percent by other technique ) . the crystalline growth of the cylindrical - si3n4 and the ratio of its longitude to its diameter are increased with the addition of nano - al2o3 . a uniform microstructure and an fined crystal as well as more sialon phases can be obtained in the si3n4 ceramics through the addition of that
实验结果表明：在碳管炉中、氮气保护下进行烧结，添加剂为纳米al _ 2o _ 3粉末时，由于纳米粉末的高活性、高烧结驱动力，在1650就可使si _ 3n _ 4完全地烧结，并使其致密度可达理论密度的96以上(比其它工艺高6左右) ；同时，纳米al _ 2o _ 3地加入大大促进了长柱状? si _ 3n _ 4的生长和发育及柱状晶长径比的提高，使微观结构均匀、细化，形成了更多力学性能优异的固体? sialon相，减少了不利于陶瓷材料性能的晶间玻璃相，净化了晶界。 - Sc shows no diffusion during heated between 800 ? to 1290 ? . analysis the result of all the experiments above , we can know porous matrix , nanometer re oxide particles and fine crystal structure can accelerate the active matter diffusion to the surface , and do good effect to the emission performance of cathode
阴极表面的空隙有利于活性物质的扩散；纳米尺度的稀土氧化物自身能量高，易于克服扩散激活能而进行扩散；发射过程中阴极表面的微晶化使表层晶界增多，活性物质扩散通道增多，利于扩散进行。
