1.On the face in contact with liquid metal there is a dense sintered layer where tightness of liquid metal is quite perfect.

2.Thermal conductivity is lower than other refractoriness so the Thermal loses are less than any other kind of refractory.

3.Good resistance to temperature change.

4.Low cost in furnace lining.

5.Short heating and sintering time through dry preparation Of masses.
