Technical Ceramics
Technical ceramics, also known as engineering ceramics or advanced ceramics, are high-performance ceramic materials specifically developed for demanding industrial, electronic, and high-temperature applications. Unlike traditional ceramics used for decorative or structural purposes, technical ceramics are engineered to provide exceptional mechanical strength, thermal stability, electrical insulation, wear resistance, and chemical durability under extreme operating conditions.
As a professional technical ceramics manufacturer, Mascera specializes in the custom manufacturing and precision machining of advanced ceramic components made from Alumina (Al₂O₃), Zirconia (ZrO₂), Aluminum Nitride (AlN), Silicon Nitride (Si₃N₄), Silicon Carbide (SiC), and Boron Nitride (BN). Our technical ceramics are widely applied in power electronics, semiconductor equipment, automotive systems, industrial machinery, and high-temperature processing environments.
What Are Technical Ceramics?
Technical ceramics are inorganic, non-metallic materials processed through precisely controlled powder preparation, forming, and high-temperature sintering processes to achieve superior material properties. These ceramics are engineered for performance rather than appearance.
Compared with conventional ceramics:
• Higher mechanical strength
• Greater hardness and wear resistance
• Improved fracture toughness
• Excellent thermal and electrical performance
• Superior resistance to corrosion and oxidation
Because of these characteristics, technical ceramics have become indispensable in modern industrial systems where metals or polymers cannot meet performance requirements.
Key Properties of Technical Ceramics
Mechanical Properties
Technical ceramics exhibit extremely high hardness and compressive strength. Materials such as Alumina and Silicon Carbide provide excellent wear resistance, making them ideal for sliding components, seals, bearings, and abrasive environments. Zirconia offers enhanced fracture toughness compared to many other ceramic materials, enabling improved resistance to mechanical shock and impact.
Key mechanical advantages include:
• High hardness
• Superior compressive strength
• Excellent wear resistance
• Low deformation under load
• High dimensional stability
Thermal Properties
One of the defining characteristics of technical ceramics is their ability to maintain performance at elevated temperatures.
• Alumina and Silicon Carbide withstand temperatures above 1600°C
• Silicon Nitride provides strong thermal shock resistance
• Aluminum Nitride offers high thermal conductivity combined with electrical insulation
• Boron Nitride exhibits thermal stability with low thermal expansion
These properties make technical ceramics ideal for furnace components, thermal management systems, heating elements, and semiconductor processing equipment.
Electrical Properties
Many technical ceramics provide outstanding electrical insulation performance.
• High dielectric strength
• High volume resistivity
• Low dielectric loss
• Stable insulation at high temperatures
Aluminum Nitride uniquely combines electrical insulation with high thermal conductivity, making it widely used in power electronics and LED substrates.
Chemical & Environmental Resistance
Technical ceramics are highly resistant to corrosion, oxidation, acids, and alkalis.
• Excellent chemical inertness
• Strong oxidation resistance
• Stable performance in harsh environments
• Radiation resistance for specialized applications
These properties allow technical ceramics to operate reliably in chemical processing, vacuum systems, and aggressive industrial environments.
Classification of Technical Ceramic
Materials Mascera provides advanced technical ceramics based on six major material systems:
Aluminum Oxide (Al2O3)
A cost-effective ceramic with excellent hardness, electrical insulation, and wear resistance.
Zirconium Oxide（ZrO2）
High fracture toughness and strength, ideal for structural and wear-resistant applications.
Hot-Pressed Boron Nitride (HPBN)
Machinable ceramic with excellent thermal stability and electrical insulation, used in high-temperature vacuum or inert gas conditions.
Pyrolytic Boron Nitride (PBN)
Ultra-pure and non-wetting to molten metals, ideal for semiconductor crystal growth and high-vacuum applications.
Silicon Nitride (Si3N4)
One of the strongest technical ceramics with superior mechanical properties and excellent thermal shock resistance.
Silicon Carbide (SIC)
Extremely hard and thermally conductive; SSiC and RBSiC are ideal for harsh, high-temperature, and chemically corrosive environments.
Combines high thermal conductivity with excellent electrical insulation, making it perfect for electronic substrates and heat dissipation modules.
