Various Characteristics of Ceramic Material Components for Industrial Applications

03 February 2020

Ceramic materials are quickly becoming the favourite choice for various components for industrial applications due to their special properties. Not only are ceramic materials effective in many situations, but they also are easily shaped into the necessary components with grinding and other methods. In addition, the composition of the ceramic components can be specifically designed to suit their purpose. To fully understand the scope of the usefulness of ceramic components in various industries, one must know their various characteristics. The following list provides valuable information about the ceramic materials in use today for components and their unique characteristics.

1. Alumina provides strength, stiffness, high hardness and effective wear-resistance. It comes in different grades, such as Alumina75, Alumina95 and Alumina99. Their uses include components for piston pumps, thin film circuit substrates, electromagnetic pumps, electrical insulation shells and more, depending upon the specific grade.

2. Aluminium Nitride or AIN provides high thermal conductivity along with showing resistance to corrosion and thermal shock. As a result, it is the ideal ceramic materials to use for components in aeronautical systems, electronic power components, microwaves, railways, military applications, semiconductor processors and heaters just for some examples.

3. Cordierite has an extremely high resistance to thermal shock and is widely used in heat exchangers in the gas turbines, hairdryers, water heaters and other applications where this type of resistance is crucial to the performance of the item.

4. Magnesia offers effective thermal conductivity, high-frequency characteristics and high-temperature insulation for electrical situations. It is often used in electrical parts for appliances and other items as a result.

5. Mullite has low thermal conductivity and expansion, effective creep-resistance, superior stability under exposure to harsh chemicals and durability in high temperatures. Due to these characteristics, this material is suitable for kiln rollers, thermocouple protection tubes, furnace muffles and other high-temperature products.

6. Silicon Carbide makes an extremely hard ceramic that is resistant to heat shock and high temperatures, an effective heat conductor and extremely strong. It is utilised for components in furnaces, car clutches, car brakes, bulletproof vests, and more.

7. Steatite delivers dielectric strength, high-mechanical strength, effective insulating properties and a low dissipation factor. It is used in thermostats, insulation for electrical components, lamps and electrical appliances.

8. Zirconia comes in various forms and provides effective resistance to chemicals and corrosion up to temperatures as high as 2400-degrees C. Industries widely use this material in pistons, bearings, tools, seals, nozzles and applications that handle molten metal just for some examples.

Industries must choose the right ceramic material components for their purposes for optimal results. They need to be familiar with all the above choices and reach out for professional advice and guidance when necessary.
