Solubility in Water: In soluble
Appearance and Odor: Fine blue powder, no odor.
SECTION IV - FIRE AND EXPLOSION HAZARD DATA
Flash Point: Non-flammable
Extinguishing Media: As appropriate for surrounding combustibles.
Flammable limits: None
Special Fire Fighting Procedures: In fires sustained by other combustible material,
the product may undergo chemical change with the evolution of heat and toxic,
irritant sulfur dioxide gas. Respiratory and eye protection required for fire fighting
personnel.
Unusual Fire and Explosion Hazards: None
SECTION V - REACTIVITY DATA
Stability: Stable under normal conditions up to 350
o
C.
Condition to Avoid: Avoid contact with acids and other incompatible and also
excessive dust generation.
Incompatibility (Materials to avoid):
Calcium carbonate ignites on contact with fluorine. It is incompatible with acids,
alum, and ammonium salts and mercury/hydrogen mixtures.
Hazardous Decomposition or Byproducts: Can produce calcium oxide if thermally
oxidized. Contact with acids of ultramarine liberates hydrogen sulfide, a highly
flammable toxic gas. At temperature above 400oC in the presence of air, an
exothermic reaction can occur with an evolution of sulfur dioxide.
