Advanced Synergistic Degassing Technology
The Vacuum Deaeration Tank is designed to eliminate microbubbles in ceramic slurries by combining a deep vacuum degree of 0.09 Mpa with active stirring. This synergy ensures that even high-viscosity mixtures are thoroughly degassed, which is a critical step for high-precision tape casting and multilayer ceramic processing.
High-Purity 304 Stainless Steel Construction
To maintain the strict purity requirements of electronic ceramics, the entire tank is fabricated from 304 stainless steel. This material offers superior corrosion resistance against various solvents and binders used in alumina, aluminum nitride, and glass-ceramic formulations, ensuring zero metallic contamination during the deaeration cycle.
Integrated Mixing & Homogenization
Equipped with the YN 100-200 mixing device, the system features dual mixing blades with a speed range of 0–130 rpm. This allows for continuous homogenization while degassing, preventing particle sedimentation and ensuring a uniform slurry consistency throughout the batch, from R&D samples to industrial production.
Comprehensive Safety & Automation
Safety is paramount in pressurized vacuum systems. Our tank incorporates multi-layered protection, including real-time vacuum monitoring and an automatic pressure relief system. The delivery pressure is strictly managed below 3 kg/cm², providing a safe and reliable method for transferring processed slurry to casting or molding machines.
Industrial Versatility & Compatibility
This equipment is highly compatible with a broad spectrum of ceramic materials. Whether processing functional coatings, electronic pastes, or dielectric slurries for MLCC, the customizable volume options (5L to 50L) and robust design make it an essential tool for material scientists and production engineers alike.
Mobility & Operational Ergonomics
The tank base is designed with heavy-duty rubber swivel casters, facilitating easy movement across laboratory or cleanroom floors without causing surface damage. The compact 200W/220V configuration makes it easy to integrate into existing production lines with minimal setup requirements.

Frequently Asked Questions
Trapped air bubbles in ceramic slurry can lead to pinholes, cracks, and dielectric breakdown in the fired ceramic part. Vacuum deaeration removes these microbubbles, ensuring a dense and uniform green tape during casting.
Stirring continuously moves the slurry, bringing bubbles trapped at the bottom to the surface where the vacuum can extract them more efficiently. It also prevents heavy ceramic particles from settling during the process.
Yes, the 304 stainless steel construction and specialized sealing systems are designed to be compatible with a wide range of aqueous and organic solvent-based slurries used in electronic ceramic manufacturing.
The system includes an integrated pressure gauge for real-time monitoring and an automatic pressure relief valve that triggers if the internal pressure exceeds the safety threshold, ensuring operator safety.
While the standard volume configuration is 10L, we offer customized tank capacities ranging from 5L to 50L to meet both R&D laboratory demands and scale-up industrial production needs.
The tank utilizes managed delivery pressure kept strictly below 3 kg/cm², providing a safe, controlled, and reliable pneumatic transfer method to move the homogenized slurry directly to casting or molding equipment.
