Embodiment 1
[0018] Embodiment 1: get nanometer MgO: nanometer La 2 o 3 : Nano-CaO: Nano-SiO 2 Mass ratio=0.15:0.15:0.3:0.4 mixture (accounting for 10% of the total mass of the precursor powder) mixed with 88wt% silicon carbide powder, 2wt% phenolic resin, and the same weight of water at room temperature to form a suspension, after electric stirring Insert a 1000W high-power ultrasonic transducer into the suspension after stirring for 5 minutes, and insert a 1000W high-power ultrasonic transducer into the suspension after stirring with an electric stirrer for 5 minutes. Start the ultrasonic generator and apply a pulsed ultrasonic field. After working for 20 minutes, the obtained suspension is filtered, dried, pulverized and sieved, and put into a mold for compression molding. The green body is heat-treated to remove the binder, and the temperature is programmed in a vacuum carbon tube furnace, and the temperature is kept at 1350°C for 1 hour, and at 1380°C for 30 minutes, then the tempe...
Embodiment 2
[0019] Embodiment 2: get nanometer BeO: nanometer Ce 2 o 3 : Nano-CaO: Nano-SiO 2 Mass ratio=0.2:0.2:0.4:0.2 The mixture (accounting for 5% of the total mass of the precursor powder) is mixed with 90wt% silicon carbide powder, 5wt% phenolic resin, and the same weight of water at room temperature to form a suspension, which is stirred electrically Insert a 1500W high-power ultrasonic transducer into the suspension after stirring for 5 minutes, and insert a 1500W high-power ultrasonic transducer into the suspension after stirring with an electric stirrer for 5 minutes. Start the ultrasonic generator and apply a pulsed ultrasonic field. After working for 20 minutes, the obtained suspension is filtered, dried, pulverized and sieved, and put into a mold for compression molding. The green body is heat-treated to remove the binder, and the temperature is programmed in a vacuum carbon tube furnace. It is kept at 1380°C for 1.5 hours, and at 1430°C for 20 minutes. After the temperat...
Embodiment 3
[0020] Embodiment 3: get nanometer BaO: nanometer Lu 2 o 3 : Nano-CaO: Nano-SiO 2 Mass ratio=0.3:0.3:0.2:0.2 The mixture (accounting for 15% of the total mass of the precursor powder) is mixed with 83wt% silicon carbide powder, 2wt% PVA, and the same weight of water at room temperature to form a suspension, which is passed through an electric stirrer After stirring for 5 minutes, insert a 2000W high-power ultrasonic transducer into the suspension, and insert a 2000W high-power ultrasonic transducer into the suspension after stirring with an electric stirrer for 5 minutes. Start the ultrasonic generator and apply a pulsed ultrasonic field. After working for 20 minutes, the obtained suspension is filtered, dried, pulverized and sieved, and put into a mold for compression molding. The green body is heat-treated to remove the binder, and the temperature is programmed in a vacuum carbon tube furnace, and the temperature is kept at 1400°C for 1.5 hours, and at 1450°C for 20 minut...
