| Grade | Key Focus Areas | Applications |
|---|---|---|
| Coating Grade | Whiteness, particle size distribution, dispersibility | Paints, industrial coatings, powder coatings |
| Plastic Grade | Particle size, surface treatment, refractive index matching | Engineering plastics, transparent polymers |
| Pharmaceutical Grade (USP/ChP) | Heavy metals control, soluble barium salts, bacterial endotoxins | Medical diagnostics, X-ray contrast |
| Radiation Shielding Grade | High density and purity | Nuclear facilities, radiation protection |
- Strict distinction required between pharmaceutical and industrial grades
- Pharmaceutical products must comply with pharmacopoeia standards
- Soluble barium salts are highly toxic - follow standard operating procedures
- Dust protection measures required for industrial applications
