1. Keep away from fire and heat source. The packaging is required to be sealed and not in contact with air. It should be stored separately from reducing agents, flammable and combustible materials, metal powder, etc.

2. Store in ventilated and dry warehouse. Do not store and mix with acids and food items. When loading and unloading, handle with care to prevent package damage.

It is decomposed by high heat to produce toxic sulfide flue gas.

Avoid contact with oxide. Almost insoluble in water, ethanol and acids. Soluble in hot concentrated sulfuric acid, easy to agglomerate when dry. 600 ℃ with carbon can be reduced to barium sulfide. It can be reduced by hydrogen at 900~1000 ℃.
The staff should be well protected and the workplace should have good ventilation conditions. If accidentally touched the skin and eyes, should be immediately washed with flowing water.

It is weakly alkaline, and is reduced to barium sulfide by co-heating with carbon, and does not change color in contact with hydrogen sulfide gas.

Ultrafine barium sulfate is precipitated barium sulfate with extremely high dispersibility. Soluble in hot sulfuric acid, insoluble in water, alcohol and other solvents. It has the advantages of narrow particle size distribution, good dispersion, strong chemical inertness, good stability, acid and alkali resistance, moderate hardness, high relative density, high whiteness, and can absorb harmful rays. It is an environmentally friendly material.
