FAQ

  • Q: What are Technical Ceramics? What are the applications?

    A:

    Technical ceramics are advanced engineered compounds crafted from inorganic and non metallic materials. Compared to regular ceramics, these have superior performance in terms of thermal stability, mechanical strength, resistance to wear and chemical reactions, and to an extent inertia. The wide variety of these can be alumina, Zirconia (ZrO2), Silicon Carbide (SiC), or Silicon Nitride (Si₃N₄). Their importance can be noted in highly sophisticated fields like electronics (insulators and semiconducting parts), medical (dental implants or joint replacements), automotives (catalyst support or sensors), aerospace (heat shields and turbine blades), industrial cutting tools, and energy (fuel cell parts and nuclear reactor liners) where these serve as components from everything ranging to IMRC’s to precision systems. Advanced technologies require these materials because of their ability to sustain high degree of temperature, corrosion, or mechanical pressure.

  • Q: What are engineering ceramics? What are their application areas?

    A:

    Engineering ceramics are advanced non-metallic, inorganic materials created to provide exceptional mechanical, thermal, chemical or electrical qualities. They present extreme hardness, wear and thermal stability, and corroding resistance, frequently outperforming metals and polymers in thermally aggressive environments. These advanced engineering materials are applied in instruments of aerospace (heat shields, turbine components), automotive (brake discs, catalytic converter substrates), electronics (semiconductors, insulators), medical (dental implants, joint prostheses), and industrial-machinery (cutting tools, wear-resistant coatings) fields. Moreover, they can withstand high temperatures, pressure, and corrosion which makes them essential in advanced technologies such as energy systems (fuel cells), precision manufacturing, and even armor defense.

  • Q: What are the aluminum ceramic (Al2O3) machining processes? Can I order them from Innovacera?

    A:

    Innovacera is focused on the machining of aluminum ceramics (Al₂O₃) using ceramic high tolerance machining, grinding and polishing processes for both unfired and fired ceramics. We have various purity of alumina ceramics which are best suited for applications necessitating high levels of thermal stability, insulation, and mechanical strength. Additionally, our facilities are capable of performing laser trimming, precision grinding, and custom metallization such as Mo/Mn coatings which enable incorporation in high performance electronic, medical and industrial devices. Tailor made Al₂O₃ components are available including ceramic resistor cores of varying dimensions and purity levels of Al₂O₃ ceramic reflector with controlled porosity. We can assist you with tailored prototypes or bulk Al₂O₃ ceramic orders while assuring strict quality control and compliance to your design specifications. Contact us for custom designs.

  • Q: What is zirconia toughened alumina? What are its properties and applications?

    A:

    Zirconia Toughened Alumina (ZTA) is a composite ceramic that integrates alumina and zirconia’s properties, giving the resulting material ZTA’s impressive hardness and fracture toughness due to zirconia’s stress-induced phase transformation and microcrack toughening. With considerable strength, wear resistance and thermal stability, in addition to biocompatibility, it works excellently in medical devices (such as dental/hip prosthetic), surgical implants, cutting tools, industrial parts (pumps, valves), and electrical appliances. Economical in comparison to pure zirconium, its properties exceed that of standard alumina in tougher engineering and biomedical uses.

  • Q: What is silicon nitride ceramic? What are its characteristics?

    A:

    Silicon nitride ceramics are modern non-oxide silicate materials mostly made of Silicon nitride (Si₃N₄). They are a type of ceramic with high strength and toughness having extremely high hardness as well as excellent capability to resist high temperature, thermal shock, wear and corrosion. Its low coefficient of thermal expansion paired with good thermal conductivity enables materials to perform steadily under extreme high deep temperature and high load conditions. Silicon nitride ceramic is used extensively in engine parts, bearings, cutting tools, and silicon devices. They are also important for specific applications like high-performance Silicon Nitride Grinding Ball used for high-precision grinding as well as low-friction and high-wear resistant grinding aids and Ceramic Igniters which are fast-heated, high durable, energy efficient igniters used in gas and pellet stoves, boilers and industrial furnaces. The above properties make silicon nitride ceramics ideal for high performance engineering applications.
