Carbides and Nitrides
At Ceratem, we design and manufacture nozzles, burners, and components made of silicon carbide (SiC) and silicon nitride (Si₃N₄)—essential materials for applications in electric and gas industrial furnaces.
Silicon carbide, available in its various forms (SiC, SiSiC, RSiC), is a material with exceptional hardness, close to that of diamond. Its thermal resistance and structural stability make it an ideal choice for high-temperature and abrasive environments. Its low thermal expansion and high conductivity make it indispensable in combustion, convection, and radiation systems.
Silicon nitride, on the other hand, is renowned for its high resistance to thermal shock, making it the optimal material for manufacturing thermocouple protection tubes and components exposed to sudden temperature changes. Its structural stability and mechanical strength make it a key material in demanding industrial applications.
These materials offer extreme resistance to high temperatures, exceptional hardness and abrasion durability, along with outstanding chemical and thermal stability. Their low thermal expansion and ability to maintain performance under extreme conditions make them fundamental in industrial settings. Additionally, silicon carbide presents semiconductor properties, making it attractive for specific high-temperature electronics applications.
Carbide and nitride materials have applications in industrial sectors such as metallurgy—where they are used in refractory parts and components for combustion and radiant furnaces—and the glass and ceramics industries, where they serve in the production of supports and rollers for high-temperature kilns. They are also essential in the energy industry, in the development of components for electric and gas furnaces, as well as in the electronics industry, where silicon carbide is used as a semiconductor material in high-temperature applications.
At Ceratem, we offer comprehensive solutions with a wide range of products, from bars and rollers to supports and custom-made parts, ensuring high-performance materials tailored to the needs of each process. Our focus on innovation and quality allows us to provide products that enhance performance and efficiency in demanding industrial environments.

Ceramics for Laboratories
At Ceratem, we manufacture high-quality ceramic crucibles and laboratory products, designed to ensure optimal performance under extreme conditions. Our product line includes crucibles, boats, and various lab components, available in standard or custom designs to meet the specific needs of each application.
We use different grades of ceramics with alumina content ranging from 95%, 99%, up to 99.7%, which provide materials with high hardness, chemical stability, and resistance to elevated temperatures. These products perform exceptionally well in demanding environments, preventing issues such as cracking and degradation caused by exposure to aggressive chemicals or sudden temperature changes.
The quality of the ceramic is essential for its performance in laboratory settings and industries where precision and durability are critical. Unlike low-quality ceramics prone to cracking, our materials ensure reliability and long-term durability in analytical and experimental processes.
Advanced ceramic products have key applications in sectors such as the aerospace industry, where extreme thermal resistance is required; the implantable medical device industry, where chemical stability is crucial; and the electronics industry, which demands materials with optimal dielectric properties. They also play a vital role in energy generation and transmission, where temperature resistance and structural stability are essential.
At Ceratem, we develop laboratory ceramic solutions with a focus on quality and precision, ensuring that every product meets the highest standards.

Cordierite – Mullite
At Ceratem, we manufacture products based on cordierite–mullite (Al₂O₃–SiO₂), designed to withstand temperatures of up to 1,400 °C and provide exceptional resistance to thermal shock. Thanks to their low thermal expansion and structural stability, these materials are ideal for industrial furnace applications, electrical insulation, support trays, and various demanding solutions in high-temperature and high-wear environments.
Cordierite and mullite are minerals widely used in the production of kiln shelves and other structural elements in thermal equipment. While cordierite is naturally occurring and commonly used in industry, mullite is a material rarely found in nature and typically produced synthetically as a high-purity powder. Their combination results in materials with high mechanical strength and durability—essential characteristics for applications requiring thermal stability and corrosion resistance.
Shelves and components made from a blend of cordierite and mullite powders are shaped and sintered to ensure a homogeneous and robust structure. These materials are highly resistant, rigid, and capable of supporting heavy mechanical loads in high-temperature environments. However, proper handling and drying before use are essential to prevent cracking or air bubbles during thermal exposure.
Industrial applications of cordierite–mullite include use in high-temperature furnaces, heaters, electrical insulation, and support trays for manufacturing processes. Their resistance to thermal shock and chemical stability make them a reliable choice for industries that require high-performance ceramic materials.
At Ceratem, we develop optimized cordierite–mullite solutions to ensure maximum performance in demanding industrial applications.
