Core consumables and performance analysis in the high-temperature experiment of the corundum ark

A corundum boat is a laboratory consumable made of high-purity aluminum oxide. Due to its excellent high-temperature resistance, corrosion resistance, and mechanical strength, it plays a key role in high-temperature experiments, material preparation, and industrial production. I. Material Properties and Structural Advantages The core material of the corundum boat is α-aluminum oxide (commonly known as corundum), which has a stable crystal structure and the following significant characteristics: High-temperature performance: The corundum boat can operate stably for a long time in an environment exceeding 1600℃, far exceeding the temperature limit of traditional experimental containers. For example, when preparing lithium-ion battery and capacitor materials, it can carry graphite paper and carbon powder for high-temperature reactions. Chemical inertness: It does not easily react with other chemicals at high temperatures and is suitable for acidic, alkaline, or corrosive environments, ensuring the accuracy and reliability of experimental data. Thermal shock resistance: The corundum boat can withstand rapid cooling and heating changes and is not easily cracked, resulting in a long service life. For example, even after repeated heating to 1200℃ and natural cooling in a tube furnace, it can still maintain its structural integrity. High density and high strength: Through the slip casting process, the volume density of the corundum boat can reach more than 3.80 g/cm³, the bending strength exceeds 350 MPa, and the compressive strength is as high as 12000 MPa, capable of withstanding high temperatures.
