1. 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博士曾提出锌铝尖晶石有可能作为制备高炉陶瓷杯的原料以替代莫来石。
2. 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下保温3h ，能够一步合成出显气孔率在5以下的刚玉?莫来石?锌铝尖晶石复相材料，各物相间结合紧密，发育较好。
3. 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
   固相反应生成的锌铝尖晶石和莫来石具有较高的活性，使复相材料在1700烧后显示出更好的烧结性能，其显气孔率降低到5以下；还原性气氛阻碍了莫来石和锌铝尖晶石的生成，不利于复相材料的烧结和致密化。
4. 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
   采用天然原料高岭土二步煅烧合成刚玉?莫来石?锌铝尖晶石复相材料研究发现：天然原料中带入的杂质主要是增加液相量，促进高温下试样的烧结；当尖晶石含量较低时，试样在1300保温2h时，在1600烧后试样烧结性能相比之下较好；而当锌铝尖晶石含量较高时，天然料对试样的促烧作用不是非常明显。
5. 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
   二次煅烧及正交实验合成复相材料研究表明：轻烧温度和轻烧时间对复相材料的显气孔率影响显著；通过轻烧保温时间的进一步研究表明：含刚玉、莫来石、锌铝尖晶石的复相材料，在轻烧温度为1300 、终烧条件为1600下保温3h时，最佳的保温时间为1小时左右。
