Product Description
Description The main material of ceramic pipe is Aluminium Oxide( Al2O3). The purity varies from 60%-99.7%, density from 3.0-3.9g/cm3, and working temperature from 1000-1700ºC. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. Features and advantage Great mechanical strengthLow thermal conductivityHigh heat resistance High softening temperatureSmall thermal expansion coefficient Good cold-resistance heat-resistanceResistance to acid and alkali corrosionLong service life Technical Index | AL2O3% Composition | Density
