Daarnaast kan keramiek materiaal worden opgedeeld in drie materiaalcategorieën aan de hand van de samenstelling:

This tends to make them ideal for surge-protection applications; as there is Manage above the brink voltage and Electricity tolerance, they find use in all sorts of applications. The top demonstration of their capacity can be found in electrical substations, in which These are utilized to safeguard the infrastructure from lightning strikes. They may have speedy response, are minimal maintenance, and do not appreciably degrade from use, generating them almost best gadgets for this application. Semiconducting ceramics are used as gasoline sensors. When different gases are passed over a polycrystalline ceramic, its electrical resistance changes. With tuning into the possible fuel mixtures, really affordable devices is usually generated.

In this sort of resources, present-day will go through the fabric until joule heating brings it towards the transition temperature, at which position the circuit might be damaged and present-day move will stop. Such ceramics are utilized as self-controlled heating components in, as an example, the rear-window defrost circuits of vehicles.

Experiments with ceramic parts for fuel turbine engines are increasingly being executed. At the moment, even blades fabricated from Innovative steel alloys used in the engines' hot portion involve cooling and thorough checking of working temperatures.

Vanweë verbintenisse satisfied die Islam is hierdie tegniek vroeër reeds in Spanje toegepas en erdewerk is reeds van die 9e eeu af satisfied die sogenaamde glansglasuur vervaardig.
