High Purity 99% Alumina Tube
High purity 99% corundum(Al2O3) alumina tube is specially used for high temperature tube furnace, vacuum atmosphere furnace, sintering, annealing and CVD experiment

Introduction
High purity alumina tube can withstand very high temperature under reducing, inert or high vacuum condition. They remain good chemical resistance under high temperature, and have excellent wear and abrasion resistance.
ZYLAB High purity alumina tube is specially used for high temperature tube furnace, vacuum atmosphere furnace, sintering, annealing and CVD experiment furnace,etc.
Main Features of Alumina Tube
1. High purity: Al2O3>99%, good chemical resistance, rarely react with the sample;
2. Good temperature resistance, long-term use at 1650℃, short-term 1700℃;
3. Reasonable and scientific use, no sudden cold and hot, long service life;
4. High density of grouting molding.

Above listed standard sizes, we have plenty of stock, can delivery fast.
Other sizes, can be customized according to demand.
Note: Alumina products are sensitive to thermal shock. Try to warm up the furnace chamber slowly. A heating rate between 150℃ ~ 300℃/hour is recommended for the first 1-1.5hours, so that the alumina products can be evenly heated to reduce the impact of thermal shock.
