正交试验法于优选白瓷坯料配方中的应用

The Application of the Orthogonal Test in Optimum Seeking the Whiteware Batch

对长石、石英、龙岩土、莱阳土４种因素各取４个水平，用正交表Ｌ１６（４５）安排１６个试验，分析了这１６个试验产品的吸水率、白度、热稳定性与每种因素各水平之间的关系．得出了白瓷坯料的最佳配方。其中，长石１９，石英２１，龙岩土２１．莱阳土０．

Four levels were chosen from four kinds of factor feldspar, quartz, Longyan clay and Laiyang clay. The 16 tests were disposed according to the orthogonal schedule L16(45). The relationships among the water absorption, the whiteness and thermal stability with all the levels of every factor were analysed. The optimum formula of the whiteware batch was achieved. It contains 19 feldspar, 21 quartz, 21 Longyan clay and 0 laiyang clay.
