gahnite
Examples
- Based on the review , the main objectives of this work had been determined . the thermodynamic analysis indicated that corundum - mullite - gahnite multiphase materials can be synthesized . the investigation of x - ray diffraction ( xrd ) and scan electron microscope ( sem ) proved the validity of thermodynamics research
通过对al _ 2o _ 3 - sio _ 2 - zno体系相关反应热力学的计算表明能够合成出刚玉?莫来石?锌铝尖晶石复相材料， x ?射线衍射( xrd )和扫描电子显微镜( sem )的研究证实了热力学计算的可靠性。 - Non - isothermal kinetics study showed that the mechanism of zno - al2o3 solid - phase reaction was well fitted with cater ' s equation . active energy of solid - phase reaction derived from the experiments by the methods of ozawa equation avoiding the function of reaction mechanism was about 63 . 48kj / mol , which was almost the same value of active energy deduced from cater ' s equation
非恒温动力学分析表明：锌铝尖晶石的固相反应机理符合卡特方程；采用卡特方程的机理函数和避开反应机理函数的ozawa方程得出的活化能分别为64 . 39kj mol和63 . 48kj mol ，两值十分接近。 - It is well known that there exists a composition triangle in phase diagram for ternary system of al2o3 - sio2 - zno , responding to three high temperature phases of corundum , mullite and gahnite . through control of chemical composition and technical process , it is possible to synthesize corundum - mullite - gahnite multiphase materials theoretically
在al _ 2o _ 3 - sio _ 2 - zno三元系中，存在着一个对应刚玉、莫来石和锌铝尖晶石三物相的分三角形，在适当的配料组成和工艺条件下，是能够合成出刚玉?莫来石?锌铝尖晶石复相材料。 - Study on the synthesis of corundum - mullite - gahnite multiphase materials by one - step sintering process using high purity raw materials showed that the more the content of gahnite in multiphase materials , the high the volume expansion would be introduced in the system , which resulted in the sintering difficulty of the multiphase materials . while the content of gahnite was controlled about 30wt % and the content of mullite was about 70wt % , the densified multiphase materials can be obtained after fired at 1600 or 1700
采用高纯原料一步合成刚玉?莫来石?锌铝尖晶石复相材料研究表明：复相材料中锌铝尖晶石含量越高，则合成锌铝尖晶石时产生的体积膨胀越大，烧结性也就越差；当锌铝尖晶石含量为30wt ，莫来石含量较高为70wt左右时，在1600或1700烧后都能得到显微结构较为致密的复相材料。
