Features
1.Strong resistance ability to subversive gas and slag
2.have insulation density, small heat capacity, low thermal conductivity and strong characteristics.
3.low bulk density, high cold strength, low thermal conductivity, good mechanical impact and vibration resistance and good corrosion resistance, which can improve the service life of furnace greatly. With features of both heavy and light weight refractory products.
4.made of high pure alumina hollow sphere and alumina micro-powder as the main material in addition with some additive .
5.By shaping at high pressure, sintering at high temperature.
6.It is widely used in synthetic ammonia furnace, ethylene gas-making furnace and high temperature shuttle furnace.
7.The maximum service is 1800℃
