Our company produces the senior silicon brick, the qualitative index achieved the overseas similar product advanced level, can replace the import product. The senior silicon brick main characteristic is the purity high, transformation complete, fuses the index lowly, high temperature performance good, the contour is neat. Uses the senior silicon brick and other glass melt kiln lives reaches above 8-10, may cause to float the law glass melt kiln life to lengthen a time. At the same time also can remarkably improve the glass quality, reduces the energy consumption. Therefore, the senior silicon brick promotion and the application enhances the building materials, metallurgy and so on one of profession economic efficiency best ways.
