In electronic equipment, magnetic testing instruments and precision medical devices, magnetic interference will lead to data deviation and equipment failure. Silicon nitride balls have natural non-magnetic and insulating properties, which solve the magnetic interference problem of metal rolling balls and become the core component of anti-magnetic precision equipment.
All steel balls and stainless steel balls have magnetic conductivity. In high-frequency electromagnetic field environment, metal balls will produce magnetic induction eddy current, resulting in energy loss and component heating. Silicon nitride is non-magnetic ceramic material, which will not be magnetized and does not produce eddy current loss.
Electrical insulation performance is another key advantage. The volume resistivity of silicon nitride balls exceeds 10¹² Ω·cm, which can completely isolate current. In high-voltage electronic equipment and insulated bearings, it avoids electric breakdown and electric corrosion damage of rolling elements.
Medical MRI equipment has extremely strict anti-magnetic requirements. Metal components will interfere with magnetic field uniformity and affect imaging clarity. Silicon nitride balls are used for bearing parts of MRI auxiliary equipment, without magnetic field interference, ensuring accurate medical imaging results.
Semiconductor magnetic detection instruments also rely on silicon nitride balls. Weak magnetic signals in chip testing are easily disturbed by metal parts. Non-magnetic ceramic balls maintain stable magnetic field environment and improve detection accuracy.
For electronic sensing equipment, magnetic testing instruments and medical imaging equipment, silicon nitride balls are irreplaceable anti-magnetic rolling components. Its magnetic insulation characteristics create a stable working environment for high-precision electronic and magnetic equipment.
