Today, let's chat how to select ceramics.
Ceramics---ceramics are used to resist abrasion,They are very important.
And ceramics are divided into many kinds, commonly used is alumina ceramics, And alumina ceramics are divided into aluminum and high aluminum and pure alumina, And high aluminum is divided into 90 , 92, 95 , 96 , 99 and so on.
From the performance of alumina content is higher, wear resistance is better, but the price is also the highest.
From the economical application,95 is the most suitable ceramic.Because Rockwell hardness is above 90 and fracture toughness, it is the most ideal material for ceramic rubber lining.Therefore, the ceramic rubber liner must be 95 , Rockwell hardness is HRA90 or more, density is 3.65, compressive strength is 1500MPa,bending strength is 350MPa.
