फ्यूज्ड mullite को आधारभूत परिचय

Fused mullite bricks are commonly known as iron bricks, which are weakly acidic refractory materials. The manufacturing method is the same as the production process of fused zirconia corundum bricks, that is, the carefully selected and pretreated raw materials are put into an electric furnace to melt, and after a period of time, they are injected into the model to form. The main component is Al2O3, the content of which can reach more than 75%, and the content of SiO2 is about 15%. In addition to the corundum crystals, it is mainly mullite crystals. The glass phase is filled between the crystal phases. The density of फ्युज्ड मुलाइट ईंटहरू फ्युज्ड जिरकोनिया कोरन्डम ईंटहरू जत्तिकै उच्च छैन, तर घनत्व पनि 2.7~3.2g/cm3 पुग्छ। अपवर्तकता 1730 ~ 1800 डिग्री सेल्सियस छ। लोड नरम तापमान 1700 डिग्री सेल्सियस वा उच्च छ।
