The advantage of alumina chemical filling ball

alumina  chemical filing balls, composed of greater than 99% sintered alpha-alumina with very low impurity levels, are essentially inert in most chemical environments.


Inert alumina ceramic balls are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers.  


Inert alumina ceramic balls have stable chemical features and a low rate of water absorption, resist high temperatures and high pressure, and also resist the corrosion of acid, alkali and some other organic solvents. They can stand the change in temperature during the manufacturing process.

The main role of inert ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.


The low silica content makes 99 alumina balls an excellent choice for high temperature applications in the presence of high water partial pressures, where silica leaching must be held minimal, such as in reformers for synthesis gas production.


The low level of other impurities makes 99 alumina balls an excellent recommendation for supporting adsorbents used to purify reactive monomers such as ethylene and propylene.


The ultra low porosity, very high density and outstanding thermal shock resistance of 99 alumina balls make them ideal for regenerative burner and filtering media for the metals industry.
