Square Rectangular Corundum Alumina Boat Tray Sagger Industrial Ceramic Reheating Furnace Tray Melting Crucible
The alumina ark is a flat long groove-type high-temperature ceramic container made of α-Al2O3 as the core raw material and high-temperature sintering.It is often known as the corundum boat.The high-purity model(99%+Al2O3)has the best performance.99% high-purity model long-term use temperature 1600°C,short-term resistance 1800°C,purity decrease temperature resistance decrease;The shape is flat rectangular groove,with no cover/with cover,with hole/no hole and other variants.Customization molding process:grouting,dry pressing ,isostatic pressing molding,and then densified by high-temperature sintering.

Advantages of alumina crucible compared with other crucible:
1. Excellent high temperature performance: alumina crucible can be used at high temperatures,
has a high melting point and chemical stability, can withstand temperature conditions.
2. Good corrosion resistance: alumina crucible has good corrosion resistance to most acids,
alkali, salt and other chemical substances, which can ensure the accuracy and safety of the experiment.
3. High strength and good mechanical properties: alumina crucible has high mechanical strength and hardness,
can withstand greater pressure and vibration, not easy to break or deformation.
4. Good thermal conductivity: the alumina crucible has high thermal conductivity and can transfer heat quickly,
which is conducive to the experiment.
5. Long service life: alumina crucible has high hardness, is not easy to wear, can be used for a long time,
reduce the cost of the experiment.
