例句與用法

In early 1993 , dr . peter put forward an idea that it is possible to substitute gahnite for mullite used as the raw material for ceramic cup of blast furnace
Study on the synthesis of corundum - mullite - gahnite multiphase materials by one - step sintering process using kaolinite showed that corundum - mullite - gahnite multiphase materials with the apparent porosity less than 5 % can be obtained through sintering at 1700 for 3h
The formation of new phase such as mullite and gahnite by solid - phase reaction in multiphase materials can benefit the sintering of materials at 1700 , decreased apparent porosity to less than 5 % . reducing atmosphere inhibited the synthesis of mullite and gahnite , played a negative role in the densification of multiphase materials
Study on the synthesis of corundum - mullite - gahnite multiphase materials by two - step sintering process using kaolinite as raw material showed that impurities introduced by kaolinite mainly increased the liquid amount at high temperature , which can assist sintering of specimen . the experiment results indicated that the samples with lower gahnite content had better sinterability than others . however , if the gahnite content was relative high , the promoting effect on sinterability caused by kaolinite was not significant
Based on orthogonal designed experiment , the synthesis of corundum - mullite - gahnite multiphase materials by two - step sintering process showed that the light fired temperature and holding time mostly influenced the apparent porosity of the multiphase materials . further study on the light firing time indicated that at the light firing temperature of 1300 and died fire temperature of 1600 for 3h , the optimal light fired time was about 1h
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
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
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
