Frequently Asked Question

Do you have any question?

Firstly, We make sure the quality before the goods to be packed, if clients get the item with Substandard products, We have warranty for our clients,we will ship out the new replacements.

Al2O3 alumina is the starting material of aluminium production, both of metallic aluminium and aluminium oxide. It is porous an has a large reactive surface.

The refractive index of fused alumina is approx. 1.76, whereas that of normal glass types is approx. 1.4. The closer the refractive indices are to each other, the more transparent the system (e.g. varnishes).

Generally, we suggest to make shipment by sea which costs less. We also can follow other transportation method you asked.
