Alumina ceramic purity 99.7% corundum tube for high temperature
tube furnace
Product Description
Quality assurance
1. High heat resistance : Alumina ceramic has excellent thermal
stability,which means that it is widely used in areas where
resistance to high temperatures is essential.
2. Good wear resistance : Alumina ceramic is the material of choice
for alumina wear parts.
3. High corrosion resistance : It is insoluble in water and only
slightly soluble in strong acid and alkaline solutions. Good
chemical stability of alumina leads to high corrosion resistance.

Advantages
Alumina ceramics are the most versatile of the advanced technical
ceramics.stronger than the traditional ceramics chemically
inert-excellent corrosion resistance outstanding electrical
insulators,even at very high temperatures extremely hard-excellent
abrasion resistance are almost unaltered at 1000°C,useable up to
1700°.All alumina bodies possess very good mechanical properties
such as hardness and compressive strength. They also hold up well
under harsh conditions such as acid corrosion,high wear areas,and
sliding abrasion. They also possess very good electrical insulation
properties and have very specific thermal conductive and thermal
expansion rates.
