TECNODIECI BARIUM CARBONATE
The studies that started in the 19th century for the purpose of using barium in glass composition continue today. As a result of the studies, barium carbonate in glaze;
-Increases whiteness
-Behaves like lead oxide in glaze and has an effect on expansion
-Increases light refraction and gives elasticity to the row as in lead frits of barium tuffs at the same firing temperature
-It has been determined that it wears out refractory bricks in frit furnaces, that is, has a corrosive effect.
-BaCO3: It is found in nature as witherite mineral. It does not have commercial reserves. It is produced by precipitating barite with Na02 CO3 or CO2. When used excessively, it can cause undesirable crystallization in glaze.

Definition and Areas of Use:Barium carbonate is produced by processing barium sulfide with Sodium Carbonate at 60 to 70 degrees with soda ash method or by passing Carbon dioxide at 40 to 90 degrees
Areas of Use of Barium Carbonate,Barium Carbonate is used in many sectors. Some of these: Optical glass, Magnetic materials, barium salts, Ceramic, enamel, Fireworks, ceramic coatings, brick, tile, Frit manufacturing is widely used
99% pure barium carbonate is used in the ceramic sector. In addition to its low melting and high boiling properties, it is added to the mud recipe for dissolving soluble salts (calcium sulfate and magnesium sulfate) that cause efflorescence. It is added at a rate of 1-2%
Since Barium Carbonate is a product that is in the IMO group, that is, in the dangerous group, it requires special storage and transportation, Barium Carbonate is commonly added to the glaze formulation in the production of matte glaze in ceramic glazes and Barium satin surface and acid-resistant matte glaze is produced
It is also widely used in frit production; the surface quality, surface tension, viscosity and expansion coefficient of the produced frit are utilized.
Barium carbonate; Since it is a toxic raw material, it is included in the Hazardous Raw Materials group (IMOlu) and extra Transportation companies incur extra costs during its transportation
It is also a raw material that should be taken into consideration during its transportation and storage
Barium production in our country is almost non-existent. For this reason, a large part of the Barium requirement is imported from many countries, especially China, and this means serious foreign exchange loss. The use of the ceramic sector is approximately 9,000-1,100 tons/year.
