The specimens were prepared with high alumina fiber accounting for 0,5%,10% or 15% by mass of the total amount of amorphous silica and high alumina fiber,using
In this work,Yb2O3 and Mg O were used as sintering aids in preparing silicon nitride ceramics by gas pressure sintering( 0. 6 MPa N2atmosphere) to investigate h
Significant energy saving effects can be made through the improvement of furnace refractories,especially the thermal insulation refractories. In this study,the
