1. Porous alumina plates can withstand extreme temperatures, making them an ideal choice for high-temperature environments. 2. Porous alumina plates can resist corrosion from various chemicals, thereby extending their service life in harsh environments. 3. Porous alumina plates have a porous structure, but they have excellent mechanical strength and can provide strong support even under stress. 4. The structure of porous alumina plate reduces the risk of thermal shock, allowing it to operate effectively at fluctuating temperatures. 5. Porous alumina plates have high electrical insulation properties, making them suitable for applications that require dielectric strength.
