Materiali ceramici avanzati
Advanced ceramic materials can be used in applications where wear resistance, high temperature resistance, electrical stress resistance, corrosion resistance, or dimensional stability cannot be achieved with metals, plastics, or conventional materials. They offer advantages such as being lighter, more efficient, more durable, and reducing operating costs.
Materials We Offer
Great Ceramic offers a wide range of advanced technical ceramic materials, ensuring we have the right material for your application.
Widely used for electrical insulation, wear resistance, corrosion resistance, and industrial ceramic components such as tubes, rods, plates, substrates, sleeves, and spacers.
Often selected when a ceramic component needs higher toughness, good wear behavior, and strong mechanical performance.
Combines high strength, thermal shock resistance, and good mechanical behavior for rollers, balls, pins, wear parts, and high-stress ceramic components.
Used where thermal conductivity and electrical insulation are required together, including substrates, heat spreaders, and power electronics parts.
Considered for wear, corrosion, high-temperature, and thermal performance in seal rings, sleeves, nozzles, pump parts, and abrasive conditions.
Selected for machinability, thermal shock behavior, insulation, and non-wetting behavior in selected molten metal or high-temperature environments.
Specialty ceramics may be considered where thermal conductivity, electrical insulation, or specific performance combinations are required.
Useful for prototypes, fixtures, insulating parts, and precision components that benefit from machining without full fired-ceramic grinding routes.
Review drawings, material requirements, tolerance needs, and manufacturing route options for custom ceramic components.
Selection table
Ceramic Material Selection by Requirement
The best material depends on the property that controls the failure risk or performance target. Use the table below as a starting point for a drawing review.
| Requirement | Materials often considered | Why they may fit | Questions to confirm |
|---|---|---|---|
| Isolamento elettrico | Alumina, aluminum nitride, boron nitride, machinable glass ceramic | Strong insulation behavior with different thermal and machining profiles | Voltage, dielectric requirement, temperature, geometry, surface finish |
| Wear resistance | Alumina, zirconia, silicon carbide, silicon nitride, boron carbide | High hardness and good abrasion resistance compared with many metals | Sliding wear or impact wear, load, mating material, lubrication, particles |
| Thermal management | Aluminum nitride, beryllium oxide, silicon carbide, boron nitride | Useful when heat transfer matters and electrical behavior must be controlled | Thermal conductivity need, insulation need, heat source, assembly method |
| High temperature use | Alumina, silicon carbide, silicon nitride, boron nitride, zirconia | Different materials handle heat, thermal cycling, and atmosphere differently | Maximum temperature, continuous or intermittent use, air/vacuum/inert gas, thermal shock |
| Chemical and corrosion resistance | Alumina, silicon carbide, zirconia, selected boron nitride grades | Useful in pumps, seals, nozzles, sleeves, and chemical equipment | Chemical media, concentration, temperature, pressure, cleaning process |
| Toughness and mechanical load | Zirconia, silicon nitride, ZTA | Better fracture toughness or strength than many other ceramics | Load direction, impact risk, wall thickness, sharp corners, assembly stress |
| Machinability and prototypes | Machinable glass ceramic, boron nitride, green-machined or fired-machined ceramics | Good for design trials, fixtures, and fast-turn precision parts | Quantity, tolerance, final strength requirement, working temperature |
| Ceramic-to-metal joining | Metallized alumina, metallized aluminum nitride, brazed assemblies | Supports electrical, vacuum, feedthrough, and assembly requirements | Metal type, braze area, leak requirement, thermal cycle, dimensional control |
Manufacturing review
From Material Selection to Custom Ceramic Components
After the material family is selected, the next step is manufacturability review. Advanced ceramic components often need different process routes than metal or plastic parts.
Great Ceramic can review material choice, drawing geometry, tolerance, green machining, fired machining, grinding, polishing, lapping, holes, slots, thin walls, surface finish, prototype needs, production needs, ceramic metallization, brazing, and ceramic-to-metal assembly requirements.
