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.
