Frequently Asked Questions

What are technical ceramics?
Ceramics, defined by the broad definition of “inorganic solids”, are one of the main classes of materials, along with metals, polymers, and composites. There are several different types of ceramics, with technical ceramics (also known as engineered ceramics or advanced ceramics) being the group with the highest performing mechanical, electrical, and/or thermal properties. Their high performance is due in part to their extremely high purities which are most commonly metal compounds combined with oxides, carbides, or nitrides. Ceramics have the ability to increase product lifespan, increase efficiency, reduce overall maintenance costs, and improve performance.

What are the advantages of technical ceramics?
High Hardness
One of the most common properties of engineered ceramics is extreme hardness (& stiffness) – some are more than 4 times harder than stainless steel. This high hardness directly translates into excellent wear resistance, meaning that many technical ceramics have the ability to keep their precise, high-tolerance finish much longer than any other material.
Extreme Compressive Strength
Technical ceramics have very high strength, however, this is only when compressed. For example, many technical ceramics can withstand extremely high loads ranging from 1000 to 4000 MPa. Titanium on the other hand, which is regarded as a very strong metal, only has 1000 MPa of compressional strength.
Low Density
Another common property of technical ceramics is their low density, ranging from 2 to 6 g/cc. This is significantly lighter than stainless steel (8 g/cc) and titanium (4.5 g/cc) with only the much softer aluminum being similar in density. Due to their high hardness and low weight, technical ceramics are increasingly being used in a variety of industries in applications where no other material can match their performance & long life.
Excellent Wear Resistance
Many technical ceramics are able to withstand incredibly high temperatures while still retaining their mechanical & electrical properties. Where all metals and polymers will start to compromise their properties, technical ceramics will continue to function with consistent performance and reliability. This property makes ceramics appropriate for use in very high temperature applications like furnaces, jet engines, brake systems, and cutting tools.
Excellent Electrical Properties
Technical ceramics tend to be excellent electric insulators (high dielectric strength). They are especially useful in high-temperature applications where other materials’ mechanical & thermal properties tend to degrade. Some ceramics have low electrical loss & high dielectric permittivity; these are typically used in electronic applications like capacitors and resonators. Additionally, the ability to combine an insulator with a structural component has lead to many product innovations.
Ultra-High-Temperature Ability
Technical ceramics can function in situations where no metal (or nearly any other material) can maintain their properties. Some ceramics can operate in temperatures in excess of 1750°C, putting them in a class of their own as ultra-high-temperature materials. These ceramics have proven to be invaluable in high-temperature applications like engines, turbines, & bearings where they have increased the lifespan, performance, and efficiency.
Thermally Conductive or Insulative
Different types of technical ceramic materials have wildly varying thermal properties. There are some ceramics (Aluminum Nitride) that are highly thermally conductive and are commonly used as heat-sinks or exchangers in many electrical applications. Other ceramics are much less thermally conductive, making them suitable for a wide range of applications.
Chemically Inert & Corrosion Resistant
Technical Ceramics are very chemically stable and have low chemical solubility, making them highly resistant to corrosion. Metals and polymers cannot offer the same inertness or corrosion resistance, making ceramics a highly attractive option in many commercial and industrial applications, particularly when wear resistance is also needed.
-
What are the drawbacks of technical ceramics?
Poor Shear & Tensile Strength
With all of these advantageous properties, you may be wondering why we do not see technical ceramics more frequently. This is due to a variety of reasons, but mostly because other types of strength are tensile and shear; this is where technical ceramics strength can be 15 times less than those of metals.
High Brittleness
Another issue that can arise with technical ceramics is that they can be very brittle due to their low ductility. This means that technical ceramics have very poor impact resistance. This property is caused by technical ceramics unique atomic bonds. Metals have “metallic” bonds which are relatively low strength, however, they can bond with atoms in any direction. This ability to have many multi-directional bonds is what makes metals ductile, tough, and relatively strong. Ceramics obviously do not have metallic bonds, instead they have ionic and covalent bonds – these are very strong, however they can only bond in very specific directions. This highly organized bonding structure means that it is difficult for the atomic structure to shift, making ceramics not malleable.
Difficult to Design
Every type of technical ceramic has specific thermal, mechanical, and electrical properties that can vary dramatically depending on the operating conditions & product design. In fact, even the manufacturing process of the exact same type of technical ceramic material can drastically change its properties.
