Hazard assessment of Frits with high Bi-content

Objective: To determine the lack off, or potential hazards of frits with high Bi-content.

Compositional profiles scope of the project:

Profile1: SiO2≥5%; Al2O3<5%; 0.3≤B2O3≤34%; Bi2O3≥50%; 0.25≤ZnO≤25%

Profile2: SiO2≥5%; Al2O3<5%; 0.3≤B2O3≤34%; Bi2O3≥50%

Profile3: SiO2≥5%; Al2O3<5%; 0.3≤B2O3≤34%; Bi2O3≤30%; 0.25≤ZnO≤25%; BaO≤4
