| titleOfInvention | Thermal shock resistant boron nitride-strontium feldspar ceramic matrix composite material and preparation method thereof |
| abstract | The invention discloses a thermal shock resistant boron nitride-strontium feldspar ceramic matrix composite material and a preparation method thereof, relating to the technical field of ceramic matrix composite materials, wherein the preparation method comprises the following steps: s1: weighing h-BN powder and SrCO 3 Powder, Al 2 O 3 Powder and SiO 2 Pulverizing and mixing to obtain raw material powder; s2: ball-milling the raw material powder to prepare ball-milled powder; s3: stirring and drying the ball-milled powder to obtain raw material powder; s4: putting the raw material powder into a graphite die, and carrying out cold pressing to obtain a block raw material; s5: and sintering the block raw material to obtain the thermal shock resistant boron nitride-strontium feldspar ceramic matrix composite. According to the preparation method of the thermal shock resistant boron nitride-strontium feldspar ceramic matrix composite material, provided by the invention, boron nitride is introduced into the strontium feldspar, and the processability of the strontium feldspar is improved on the premise of not influencing the dielectric property of the strontium feldspar. |
