High-thermal-conductivity and high-quality silicon nitride ceramic substrate and preparation method thereof
The invention relates to a silicon nitride ceramic substrate and a preparation method thereof, in particular to a high-heat-conductivity and high-quality silicon nitride ceramic substrate and a preparation method thereof. The invention aims to solve the problems that the thermal conductivity and the mechanical property of the silicon nitride substrate prepared by the existing method are poor, and the equipment and the manufacturing cost are high and the batch production is difficult to realize due to spark plasma sintering. The high-heat-conductivity and high-quality silicon nitride ceramic substrate is prepared from silicon nitride powder or silicon nitride powder and aluminum nitride, rare earth oxide, magnesium powder, a plasticizer and an organic solvent. The method comprises the following steps: 1, weighing; 2, grinding, mixing and granulating; 3, dry pressing molding; and 4, air pressure sintering. According to the invention, the silicon nitride ceramic substrate with high thermal conductivity and high quality can be obtained.
