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
