Industrial Use
Silicon nitride structural parts deliver exceptional resistance to wear, corrosion, and high temperatures—ideal for demanding industrial applications.
Silicon nitride structural parts are advanced ceramic components known for their outstanding mechanical strength, wear resistance, and thermal stability. These high-performance ceramics are engineered to operate in the most demanding industrial environments where traditional materials fail due to abrasion, corrosion, or extreme heat.
Manufactured using hot-pressing and advanced sintering techniques, silicon nitride parts offer a unique combination of high flexural strength, excellent fracture toughness, and low thermal expansion. These properties make them especially effective in high-temperature, chemically aggressive, or mechanically dynamic settings.
Typical applications include:
Bearings, seals, and guides in semiconductor and automotive industries
Insulating components in high-voltage and RF electronics
Nozzles, plungers, and sleeves in chemical processing systems
Structural supports and fastening components in high-temperature kilns
Precision mechanical parts in aerospace and energy sectors
Unlike other ceramics such as alumina or zirconia, silicon nitride parts can withstand rapid thermal cycling, maintain stability at temperatures up to 1400°C, and resist chemical degradation from acids, alkalis, and molten metals. This makes them a preferred choice for wear resistant ceramic components where durability and performance are critical.
We offer custom silicon nitride structural parts tailored to your exact specifications, including special shapes, sizes, and connection methods. Our engineering team works closely with clients to ensure optimal material selection and integration with metal or composite systems.
With a smooth surface finish, lightweight design, and long service life, our structural ceramic components significantly reduce maintenance costs and downtime in industrial operations.
Ceramic pipe sleeves are protective linings made from advanced ceramic materials, designed to enhance the durability and lifespan of pipes in various industrial applications. They offer exceptional resistance to abrasion, corrosion, and high temperatures, making them ideal for challenging environments.
These sleeves are typically produced using a combination of high-purity alumina and other ceramic materials, which are processed at high temperatures to create a dense, wear-resistant lining. The result is a product that can withstand the rigors of heavy use while maintaining its structural integrity.
Recently, 95% alumina ceramic sleeve-lined pipes , elbows, and T-joints have been widely adopted in lithium battery material conveying systems .
Producing large-diameter ceramic sleeves poses a significant challenge for most manufacturers due to difficulty in controlling deformation during sintering. Furthermore, it requires advanced isostatic pressing equipment to ensure dimensional precision and structural stability.
Successfully manufacturing these high-precision components is a strong indicator of a company’s production capabilities and technical expertise in ceramic processing.
At present, our factory owns both the state-of-the-art wear-resistant ceramic pressing facilities and the engineering know-how to deliver reliable, large-size ceramic sleeves tailored for demanding industrial applications.

304 stainless steel plate has very good formability and can be readily welded by all common methods. Its combination with ceramic lining offers enhanced performance in wear resistance and structural stability.
Ceramic sleeve lined pipes are engineered by embedding a high-purity alumina ceramic sleeve into a robust steel outer pipe. This combination significantly improves resistance to wear, corrosion, and extends service life in highly demanding environments.
Thoroughly remove rust and debris from the steel pipe surface to ensure optimal adhesion.
Install sleeves precisely. Fill any gaps and seal joints to ensure a continuous ceramic layer inside.
