Graded Bubble Alumina Introduction

1)for 5~25 tons, it takes around 10~15days. 2)For 26~200 tons,20-40days We will try to deliver it with the promise of quality guarantee as soon as possible

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

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).

Yes, No problem, but Customer resposiable for the charge.

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.

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.

fused aluminum oxide products do not have a known shelf life. As long as the product is maintained in the original sealed container and stored in a cool, dry, ventilated area, our product will last indefinitely

Yes, Sample cost below 5 kgs can be refunded when bulk order confirmed,But freight cost for more than 1kg don’t be refunded.

If you take a (1) inch space and add wires to it, the number of openings within the 1″ space is defined as mesh. For example, if the 1″ space has ten openings for particles to fall through, then that sieve would be called a 10 mesh sieve. Typical sieve

When processing minerals in a furnace, materials can either be melted or sintered.  When materials are melted during the production process the minerals go from a solid state, to a liquid state, then is re-solidified during the cooling process creating uniformity in the chemistry throughout the entire batch. The sinerting process

Yes. According to NIOSH, Brown Aluminum Oxide could be a viable substitute for consumers looking for safer alternative materials to high crystalline silica content abrasive products.
