<h2 style="text-align:left;font-family:Arial, Helvetica, sans-senif;">
<span style="font-family:Arial;font-size:16px;font-weight:normal;line-height:1.5;">Barium carbonate (chemical formula: BaCO3) is called toxastonite because it is easier to obtain from natural minerals and it is toxic. Barium carbonate is a white precipitate that is insoluble in water and is a common inorganic salt.</span>

<span style="font-size:18px;"><span style="font-size:24px;color:#FFFFFF;background-color:#006600;">production method</span><br />
<span style="font-size:16px;">Method One: Carbonization In the yttrium sulfide solution (see Preparation of sulphide), carbon dioxide gas is carbonized to obtain a barium carbonate slurry which is desulfurized and washed, vacuum filtered, dried at 300° C., and pulverized to obtain a barium carbonate finished product. The reaction formula is as follows: BaS+CO2+H2O→BaCO3↓+H2S↑ metathesis method The metathesis reaction of yttrium sulphide and ammonium carbonate, followed by washing, filtration, drying, etc., to obtain the barium carbonate finished product. The reaction formula is as follows: BaS+ (N</span><br />
<span style="font-size:16px;">H4)2CO3→BaCO3↓+(N</span><br />
<span style="font-size:16px;">H4) 2S poisonous stone conversion method reacts toxic heavy stone ore with ammonium salt to form soluble barium salt, and ammonium carbonate is used for recycling. The soluble barium salt is added with ammonium carbonate to precipitate refined barium carbonate, which is filtered and dried to obtain barium carbonate. Finished product. The resulting mother liquor is recycled for recycling.</span> <br />
<span style="font-size:24px;color:#FFFFFF;background-color:#006600;">use</span><br />
<span style="font-size:16px;">It is mainly used in the manufacture of optical glass, picture tube glass, and neodymium magnetic materials and capacitors, as well as steel carburizing and metal surface treatment. It is a raw material for the manufacture of other barium salts and ceramics, enamels, paints, coatings, rubbers, and welding rods. Also used as a water purifying agent and rodenticide, oxidation catalyst.</span><br />
