>> Product Description
Al2O3 ceramic glass tubes are made from high-purity aluminum oxide (typically ≥ 99.7%), offering exceptional thermal stability, corrosion resistance, and electrical insulation. These tubes are ideal for use in high-temperature environments such as laboratories, furnaces, vacuum chambers, and electronic devices.
With excellent mechanical strength and low thermal conductivity, alumina tubes are widely used in scientific research, industrial manufacturing, thermocouple protection, and insulating applications. The smooth inner and outer surfaces ensure precise performance and durability under harsh conditions.
