Alumina filler ball of inert ceramic ball

There are many kinds of inert ceramic balls.The alumina material is divided into grinding balls,regenerative balls,refractory balls,filler balls and so on.In this article,we will focus on the use of inert alumina filler balls (solid).

Inert,as the name suggests,it does not participate in chemical reactions.It is made of alumina powder after being calcined into industrial powder,and then calcined into high-density structure by rotary kiln and tunnel kiln.This dense and stable chemical structure looks like ceramic,so it is called alumina ceramic ball.

Different from general ceramics,alumina ceramics have a Mohs hardness of 9,second only to diamonds,and their compressive strength and impact resistance are far from comparable to ceramics.At the same time,they have the same advantages as ceramics:Acid and alkali corrosion resistance,these are good The performance makes the inert alumina filler ball more and more widely used in industry.

At present,inert alumina filler balls are more widely used in high-aluminum products,such as 90/92/95/99,which are widely used in chemical and petroleum industries as fillers.The materials required by these industries need to withstand the corrosion of strong acids and alkalis and other chemical solvents,and must withstand high temperature and high pressure,and can not participate in the reaction.These requirements happen to meet the needs of alumina filler balls,so it is highly valued.
