Think your mixing your pads up, ceramic pads do produce dust but its much finer and does not stick to wheels.
They are quite good under a wide range of temperatures for consistent performance. But race pads they are NOT as they dont absorb heat as well as semi-metaillic pads etc will, which can increase brake system temperatures.
They are good if you don't like brake dust on your wheels but not really suitable for racing or if your heavy on the brakes
I'd probably get them only if I wanted to not have brake dust on my wheels and i didn't track the car
