Ceramic components are manufactured from high-performance ceramics, fine ceramics and high-tech ceramics. Alumina, zirconia, silicon nitride, aluminum nitride, and silicon carbide are frequently used ceramic materials. They possess superior toughness, hardness, electrical insulation, good heat resistance, wear resistance, and oxidation resistance. In addition, they exhibit outstanding mechanical, acoustic, light, thermal, electrical, and biological characteristics.
Ceramic components feature a number of remarkable properties, including high temperature resistance, high strength, high hardness, high wear resistance, corrosion resistance, and oxidation resistance. They are capable of withstanding harsh working environments that are challenging for metal and polymer materials, becoming the key to the realization of numerous emerging science and technologies. In the fields of energy, aerospace, machinery, transportation, metallurgy, chemical industry, electronics, and biomedicine, ceramic components have extensive application prospects.
Manufacturing of Ceramic Components
Sintering: The majority of ceramic components are produced by sintering compacted powder. According to the sintering pressure, there are various types of sintering techniques: atmospheric pressure sintering, pressureless sintering, vacuum sintering, hot-press sintering, hot-isostatic press sintering, and atmosphere sintering. Binders are frequently added during the sintering process to improve the flow characteristics of the powder, resulting in higher density in final components.
Machining: The majority of advanced ceramics are extremely brittle and hard materials that are challenging to process. Therefore, advanced processing equipment and mature processing experience are required to process ceramic components with intricate shapes, high dimensional precision, low surface roughness, and high dependability. The processing services that Unipretec can offer include conventional mechanical processing, such as cutting, grinding, and drilling, and threaded holes can also be machined; laser cutting, which has a fast processing speed and can cut non-penetrating blind grooves. The maximum cutting thickness can reach 5mm, and cutting with an incredibly small gap width can be achieved. Internal and external grinding can obtain high precision, and the quality is reliable; Automatic centerless grinding and chamfering have a high efficiency and cost low. For a variety of ceramic products with complex shapes and high precision requirements, CNC machining is appropriate. Furthermore, Unipretec can conduct polishing process, with zirconia surface roughness <Ra0.02 and alumina surface roughness <Ra0.1. The most efficient processing method that can meet product accuracy requirements will be selected based on the various product forms and precision requirements.
Application of Ceramic Components
Ceramic components are commonly employed in the areas of high temperature, corrosion, electronics, and optics. With their outstanding performance, they stand out as an emerging material in the material field. They have drawn a lot of attention from the public and will play an essential role in the future society.
Electrical Ceramic Components
Electronic ceramic components are mostly used in chips, capacitors, integrated circuit packaging, sensors, insulators, ferromagnets, piezoelectric ceramics, semiconductors, and superconductors. Alumina, zirconia, aluminum nitride, and silicon nitride are the primary materials used. Typical products include ceramic substrate, ceramic insulator, ceramic washer and spacer.
Structural Ceramic Components
Structural ceramic components are commonly used in wear-resistant parts, pump and valve components, engine components, heat exchangers, biological components and armored equipment. Silicon nitride, silicon carbide, zirconium dioxide, boron carbide, titanium diboride, alumina. are the main materials. Their typical properties are: high hardness, low density, high-temperature resistance, creep resistance, wear resistance, corrosion resistance and excellent chemical stability. Consequently, ceramic components progressively replace costly ultra-high-alloy steel in various situations or are used in situations where metal materials are inappropriate. Typical products include oil and gas plunger pumps, valve balls and seats, sealing rings, and high pressure washer pump piston.
Aerospace Ceramic Components
Aerospace ceramic components mainly involve infrared stealth and camouflage coatings, ceramic bearings, ceramic radome materials for missiles, aircraft brake disc materials, bulletproof armor ceramics for helicopters, ceramic diaphragm materials for satellite batteries, and so forth. The nose cone and the wave-transmitting ceramic radome are critical components in rocket and missile launch. They need to withstand the friction and erosion caused by high-temperature airflow. The materials must have excellent high-temperature strength and great oxidation resistance. Only ceramic materials can satisfy these requirements.
