Ceramic Knowledge / FAQ

When selecting materials for ceramic bearing balls, zirconia (ZrO2) and silicon nitride (Si3N4) are the two most common choices. Both materials offer excellent hardness, corrosion resistance, and high-temperature performance, but they differ significantly in several technical aspects.

A metal ceramic heater (MCH) is a compact, high-efficiency heating element that embeds a resistive circuit inside a ceramic body—most commonly alumina (Al₂O₃) or silicon nitride (Si₃N₄).

plunger ceramic pump is a type of positive-displacement pump where the plunger is made from wear-resistant ceramic (alumina or zirconia), offering high precision and durability.

icro Ceramic Pumps equipped with plunger ceramic components are gaining widespread popularity in modern precision dosing systems. Their compact structure, chemical stability, and extended lifespan make them ideal for high-accuracy fluid control across pharmaceutical, cosmetic, and laboratory applications.

​In pharmaceutical aseptic production, proper cleaning and sterilization of a ceramic filling pump is critical for maintaining hygiene, product quality, and GMP compliance. The key processes used are Clean-in-Place (CIP) and Sterilize-in-Place (SIP), which eliminate residues and microorganisms from internal pump surfaces—especially from the ceramic piston pump components such as the ceramic plunger and pump sleeve.

Many users of Alumina Ceramics have observed that after prolonged exposure to sunlight, some components begin to show visible discoloration—often a yellowish or dull hue on the surface. While this change does not impair performance, it raises concerns about the long-term stability and appearance of the material.

Aluminum Nitride Ceramics (AlN ceramics) are widely used in high-performance applications due to their excellent thermal conductivity, electrical insulation, and high-temperature resistance. However, some users may notice slight color differences among different batches of AlN ceramics—such as light gray, off-white, or pale yellow shades. These variations are normal and do not affect the material's performance.

Selecting the correct ceramic washer thickness involves balancing electrical insulation, thermal management, and mechanical strength considerations to ensure reliable, safe, and efficient device operation.

Ceramic materials—especially technical ceramics—have become indispensable in modern industry due to their outstanding properties. These materials are widely used across sectors such as electronics, mechanical systems, metallurgy, energy, aerospace, chemicals, and medical equipment, often replacing metals in demanding applications.

Alumina ceramic tubes are widely used in high-temperature industrial applications due to their high-temperature stability, excellent thermal shock resistance, and outstanding durability. One of the most common applications is ceramic tubes used in high-temperature furnaces for heat treatment, sintering, and thermocouple protection.
