Alumina Tube
Introduction of Alumina Tube:
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:
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.
Standard Sizes(Dia*L):
50*700mm 50*1000mm 50*1200mm 50*1400mm
60*700mm 60*800mm 60*1000mm 60*1200mm
80*1000mm 80*1200mm 80*1400mm 80*1500mm
100*1000mm 100*1200mm 100*1200mm
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.
