SLQ-MCEG-99 is our Electronic-Grade vs. SLQ -MCBG-98 IS Battery-Grade Manganese Carbonate

Including particle size requirements, heavy metal limits, and impurity requirements

I. Core Position & Main Content (Chemical)

- Electronic-grade (for soft ferrite)
Mn ≥ 45.0–47.0%, MnCO₃ ≥ 99.5%
Focus: stable magnetic properties, impurities do not affect sintering

- Battery-grade (for LiMn₂O₄ / lithium batteries)
Mn ≥ 44.0–45.0%, MnCO₃ ≥ 99.0%
Focus: low alkali metals, low heavy metals, high electrochemical stability

II. Heavy Metals & Key Impurities (Chemical, unit: %)

Heavy Metals (stricter for battery-grade)

- Fe: electronic-grade ≤ 0.005; battery-grade ≤ 0.001

- Pb: electronic-grade ≤ 0.005; battery-grade ≤ 0.001

- Cu: electronic-grade ≤ 0.003; battery-grade ≤ 0.001

- Ni / Cr / Zn: electronic-grade ≤ 0.003–0.005; battery-grade ≤ 0.001–0.002

- Cd / Co: not mandatory for electronic-grade; battery-grade ≤ 0.001 (required)

Alkali / Alkaline Earth Metals & Anions (much stricter for battery-grade)

Na / K: electronic-grade ≤ 0.003–0.005; battery-grade ≤ 0.003–0.005

- Ca / Mg: electronic-grade ≤ 0.003–0.005; battery-grade ≤ 0.002–0.003

- Cl⁻: electronic-grade ≤ 0.01–0.06; battery-grade ≤ 0.003–0.005

- SO₄²⁻: electronic-grade ≤ 0.02–0.05; battery-grade ≤ 0.01–0.02

- SiO₂ / Al₂O₃: electronic-grade ≤ 0.01; battery-grade ≤ 0.001

III. Particle Size & Physical Indicators

Particle Size (D50, μm)

- Electronic-grade: 8–13 μm (laser particle size); or FSSS < 4.0

- Battery-grade: 3–10 μm (typically 4–8 μm), narrower particle distribution (Span < 1.2)

Density & Morphology

- Bulk density: electronic-grade 0.4–0.7 g/cm³; battery-grade 0.8–1.2 g/cm³

- Tap density: electronic-grade 1.2–1.6 g/cm³; battery-grade ≥ 1.8 g/cm³

- Morphology: electronic-grade — spherical / subspherical; battery-grade — spherical / ellipsoidal, good flowability, low agglomeration

IV. Summary of Key Differences

- Chemical specifications: Battery-grade has stricter limits for heavy metals, Cl⁻, SO₄²⁻, SiO₂; electronic-grade has slightly higher Mn content and tighter control for sintering-related impurities.

- Physical specifications: Battery-grade features finer particle size, narrower distribution, higher tap density; electronic-grade has slightly coarser particles and lower bulk density.

- Core logic: Electronic-grade ensures magnetic performance and sintering stability; battery-grade ensures electrochemical stability, low self-discharge, and long cycle life.
