Detailed Product Description
Detailed Product Description
Inert aluminum oxide ceramic balls are widely used in many fields, including petroleum, chemical engineering, fertilizer production, natural gas and environmental protection. They are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers. Having stable chemical features and a low rate of water absorption, they can resist high temperatures and high pressure. They can also resist the corrosion of acid, alkali and some other organic solvents, and are able to stand the change in temperature during the manufacturing process. The main role of these ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.

Order notice
(1) When ordering, customers should detail the basic information, including reaction size and operation temperature.
(2) Size and type of products, total contents of aluminum and silicon should be pointed out.
(3) Because the insert ceramic balls are naturally close-packed in reaction vessel, the customer should settle their necessary quantities according to actual packing volume, and a spare quantity of 15 to 20 percent is necessary.
