Silicon nitride composite ceramic die material, and preparation method and application thereof

HU TIEWU / WU ZHENGREN / KANG YIQUN / LAN YOUZHONG / SUN QINGLE

The invention discloses a silicon nitride composite ceramic die material, and a preparation method and an application thereof. The die material is composed of Si3N4, Al2O3, MgO, AlN, Y2O3, CeO2, Cr3C2, TiN, TiC, Mo2C and MoSi2. The preparation method comprises the steps of raw material mixing, ball milling, drying and sieving. Dies made by using the silicon nitride composite ceramic die material have the advantages of high strength, low thermal expansion coefficient, long service life, and improvement of the production efficiency and the product quality.
