A bat can fly in the night without an accident because it is using ultrasonic waves to create a 3D picture of the environment in its brain. Therefore a bat is able to detect sensorily the next obstacle in the dark. Human beings lack this ability.
But there is a solution:

They are tiny and look like electronic buttons but they help us every day. Piezo ceramic supersonic sensors are used to "see" hidden obstacles in cars to prevent accidents.
These piezo ceramics are made out of PZT (lead zirconate titanate) powder sintered at temperatures from 1200 to 1300 °C. The refractories must withstand these temperatures, but more important is that there is no reaction between the setter plate and the PZT powder.

Our refractories out of zirconia are used in this process.
