Silicon Nitride Grinding Jar XN-MJ-SN

SKU: XN-MJ-SN

Silicon Nitride Grinding Jar XN-MJ-SN is a mold-formed silicon nitride (Si₃N₄) ceramic jar for ball-mill grinding, with extremely smooth inner and outer walls that keep material from sticking. This tough, high-strength metal-free ceramic offers wear resistance, is chemically inert and heat-resistant to various solvents, and provides strong acid and alkali resistance together with impact resistance.

A large-radius (R-angle) bottom reduces material build-up for high grinding efficiency and long service life. Supplied with a matching lid, and sizes are customizable to suit your mill and sample.

Product Introduction:

The XN-MJ-SN Silicon Nitride Grinding Jar is a mold-formed silicon nitride (Si₃N₄) ceramic jar for ball-mill grinding. Its inner and outer walls are extremely smooth, so material does not stick to the walls during grinding. As a tough, high-strength metal-free ceramic, it offers wear resistance, is chemically inert and heat-resistant to a wide range of solvents, and provides strong acid and alkali resistance along with impact resistance — making it well suited to thermal-shock-prone and chemically demanding grinding where metal contamination must be avoided. The bottom is formed with a large R-angle to reduce material sinking and build-up while grinding, supporting high grinding efficiency and a long service life. The jar is supplied with a matching lid, and sizes can be customized to suit the customer’s mill and batch requirements.

Technical Specifications:

Parameter Specification
Product Code XN-MJ-SN
Material Silicon nitride (Si₃N₄) ceramic
Wall Finish Mold-formed; extremely smooth inner and outer walls
Resistance Wear resistance; chemically inert and heat-resistant to various solvents; strong acid and alkali resistance; impact resistance
Bottom Design Large R-angle to reduce material build-up
Lid Included
Available Sizes Customizable to order

Application Areas:

Grinding jar for planetary and roller ball mills
Tough, impact-prone sample grinding that requires a metal-free jar
Grinding in various solvents and chemically demanding media
Grinding in strongly acidic or alkaline chemistry
High-temperature grinding applications
Battery R&D — metal-free grinding of cathode, anode, and precursor powders

Maintenance:

Clean the jar and lid thoroughly after each use to prevent cross-contamination
Dry the jar completely before storage
Inspect the sealing surface and lid for chips or cracks before each run
Avoid impact, thermal shock, or dropping that could chip or crack the ceramic

Safety Notes:

Ensure the lid is properly sealed before milling
Do not exceed the jar’s rated load or the mill’s capacity
Handle the ceramic jar carefully to avoid chipping or breakage

Specifications are provided for reference and may be adjusted to suit specific process requirements. Jar size and configuration are specified at order time.

Note: Specifications listed above are typical and for reference only. Actual performance depends on the material, media, and mill. The XN-MJ-SN silicon nitride jar is a tough, high-strength metal-free ceramic that is chemically inert and heat-resistant to a wide range of solvents, with strong acid and alkali resistance and excellent impact resistance — a good fit for thermal-shock-prone and chemically demanding grinding. Compared with the harder XN-MJ-SIC Silicon Carbide Grinding Jar, silicon nitride trades some hardness for greater toughness and impact resistance; for the densest, non-toxic high-purity work the XN-MJ-ZR Zirconia Grinding Jar is the premium alternative, while the XN-MJ-AL Alumina Grinding Jar is the economical choice for routine grinding. Silicon nitride jars run well in planetary mills such as the XN-YXQM Series.
