The only difference is that ceramic brake pads are much more durable in comparison to ceramic pottery.
Difference between metallic and ceramic brakes which to buy.
The ceramic linings also keep the brake fluid cooler than the metallic pads which typically add up to the cost.
The ceramic compounds and copper fibers allow ceramic pads to handle higher brake temperatures with less heat fade provide faster recovery after the stop and generate less dust.
Ceramic brake pads are the most expensive brake pads and they cost much more than the semi metallic brake pads.
These brake pads are made using ceramic material much like you d find in pottery only much more dense in order to be able to withstand the extreme pressure and heat of braking.
Produce less dust than semi metallic pads resulting in cleaner wheels.
Quieter than semi metallic pads.
Copper is also used to increase stopping power and to aid in heat transfer.
It is because ceramic pads are more efficient and have an excellent braking power compared to the semi metallic pads.
However there are some disadvantages to metallic brake pads.
That is the main reason why ceramic pads are expensive.
As far as price goes metallic brake pads tend to fall somewhere between organic and ceramic pads.
Metallic or semi metallic linings on the other hand fall somewhere between the organic and ceramic range so they are relatively less expensive than their ceramic counterparts.
