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
早在1993年， peter博士曾提出鋅鋁尖晶石有可能作為制備高爐陶瓷杯的原料以替代莫來石。
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
在1700下保溫3h ，能夠一步合成出顯氣孔率在5以下的剛玉?莫來石?鋅鋁尖晶石復相材料，各物相間結合緊密，發(fā)育較好。
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
固相反應生成的鋅鋁尖晶石和莫來石具有較高的活性，使復相材料在1700燒后顯示出更好的燒結性能，其顯氣孔率降低到5以下；還原性氣氛阻礙了莫來石和鋅鋁尖晶石的生成，不利于復相材料的燒結和致密化。
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
采用天然原料高嶺土二步煅燒合成剛玉?莫來石?鋅鋁尖晶石復相材料研究發(fā)現(xiàn)：天然原料中帶入的雜質主要是增加液相量，促進高溫下試樣的燒結；當尖晶石含量較低時，試樣在1300保溫2h時，在1600燒后試樣燒結性能相比之下較好；而當鋅鋁尖晶石含量較高時，天然料對試樣的促燒作用不是非常明顯。
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
二次煅燒及正交實驗合成復相材料研究表明：輕燒溫度和輕燒時間對復相材料的顯氣孔率影響顯著；通過輕燒保溫時間的進一步研究表明：含剛玉、莫來石、鋅鋁尖晶石的復相材料，在輕燒溫度為1300 、終燒條件為1600下保溫3h時，最佳的保溫時間為1小時左右。
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
在al _ 2o _ 3 - sio _ 2 - zno三元系中，存在著一個對應剛玉、莫來石和鋅鋁尖晶石三物相的分三角形，在適當?shù)呐淞辖M成和工藝條件下，是能夠合成出剛玉?莫來石?鋅鋁尖晶石復相材料。
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
采用高純原料一步合成剛玉?莫來石?鋅鋁尖晶石復相材料研究表明：復相材料中鋅鋁尖晶石含量越高，則合成鋅鋁尖晶石時產生的體積膨脹越大，燒結性也就越差；當鋅鋁尖晶石含量為30wt ，莫來石含量較高為70wt左右時，在1600或1700燒后都能得到顯微結構較為致密的復相材料。
