Customized Corrosion-Resistant Hexagonal Boron Nitride Ceramic Plunger

Customized hexagonal boron nitride (h-BN) ceramic plungers are designed for demanding industrial environments requiring excellent corrosion resistance, 

high-temperature stability, and reliable non-wetting performance. With a unique layered crystal structure, h-BN ceramics offer outstanding chemical inertness 

and self-lubricating properties, making them ideal for precision motion and fluid control applications.

These ceramic plungers maintain structural integrity and dimensional stability under extreme temperatures and aggressive chemical conditions, while providing excellent electrical insulation and minimal friction during operation. Compared with conventional metal or oxide ceramic plungers, hexagonal boron nitride 

plungers significantly reduce wear, contamination, and maintenance requirements.

Applications

Semiconductor & Electronics Manufacturing

Used in high-temperature processing equipment and precision handling systems where chemical purity, insulation, and thermal stability are critical.

Metallurgy & Molten Metal Processing

Ideal for plungers used in aluminum, magnesium, and non-ferrous metal casting or dosing systems, preventing metal adhesion and corrosion.

High-Temperature Furnace Equipment

Applied as functional plungers or actuating components in vacuum furnaces, sintering furnaces, and controlled-atmosphere furnaces.

Chemical & Industrial Fluid Control

Suitable for corrosive or high-temperature fluid environments where conventional materials suffer from rapid degradation.
