The use of barium hydroxide should be avoided as this compound increases the pH of the cathodic film which is a known cause of pitting. The following link can be used to calculate the amount of concentrated sulfuric acid needed to increase sulfate, or the amount of barium carbonate needed to lower it.
Lubon (HB) Chemical Co.,Ltd. is one sub-company of Lubon Industry Co.,Ltd, major in producing barium chloride, barium carbonate and barium hydroxide. Our products have been well received by customers in China, and in Hong Kong, Canada, USA, Germany, Poland, Italy, Spain, etc.
Barium carbonate is also used in the manufacturing of hard ferrite magnets and several types of glasses and frit. Safety striping, such as that found on airport runways, use high refractive index glass beads which are made using barium carbonate as a primary component.
Barium carbonate powder is dense and white and is manufactured either from the mineral barite (BaSO4) or from barium chloride. Subsequently a precipitation process is used to get the carbonate form. There are several crystalline forms of BaCO3, alpha is the most stable.

compound can be used directly for the process or converted to barium carbonate. Wilsenach (1986) demonstrated the economic viability by calculating the cost of producing barium sulphide from barium sulphate. Trusler et al. (1988) developed a barium carbonate method using a two-stage fluidised bed reactor system to overcome the other problems ...
Barium carbonate is a white powder. It is insoluble in water and soluble in most acids, with the exception of sulfuric acid. It has a specific gravity of 4.275.

Mar 25, 2016· barium carbonate rotary furnace manufacturing process ... and vanadium, in order to minimize losses and improve process control. Metals that do not oxidize readily, such as nickel, cobalt, molybdenum, and copper, can be added in the furnace to take advantage of high heating rates.
Barium hydroxide ("baryta") was known to alchemists, who produced it by heating barium carbonate. Unlike calcium hydroxide, it absorbs very little CO 2 in aqueous solutions and is therefore insensitive to atmospheric fluctuations.
Barium Carbonate is manufactured from natural barium sulfate (barite) by reduction with pet coke and following precipitation with carbon dioxide. ... - Caustic lye brine purification process - Brick manufacturing - Manufacture of other barium chemicals like chloride, peroxide, nitrate etc., - For special Glass manufacturing Physical Properties ...

Barium - Wikipedia. Barium is a stone element with symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal.Because of its high stone reactivity, barium is never found in nature as a free element.Its hydroxide, known in pre-modern times as baryta, does not occur as a mineral, but can be prepared by heating barium carbonate.

Barium carbonate is prepared by treating barium sulfide with sodium carbonate at 60 to 70°C or by passing carbon dioxide at 40 to 90°C. The another method of preparing Barium Carbonate is by soda ash process, In this process sodium carbonate is added to barium sulfide solution, and the obtained barium carbonate is filtered, washed and dried.
For those countries where barium carbonate is prohibited, ... How to reduce scumming from structural bricks without Barium Carbonate? ... Scum formed during the drying process. Soluble salts within the raw materials are carried to the surface as the water is being driven off. It can also be formed by sulfurous gasses within the dryer atmosphere ...
The removal of sulphate and metals from mine water was assessed using the integrated barium carbonate process and the co-precipitation of barium sulphate with calcium carbonate.
Barium carbonate standard powder is used in the production of special glass, glazes, brick and tile industry, ceramic and ferrite industry. Barium carbonate standard powder is also used for removing of sulfates in phosphoric acid production and chlorine alkali electrolysis.
A process for the production of barium carbonate by reacting the barium sulfate under pressure with excess dilute sodium carbonate solution has now been found wherein the decomposition is conducted continuously in the following stages:

Barium carbonate is admixed with sea water to form barium sulfate, calcium carbonate, and magnesium carbonate which are removed as precipitates. The precipitates are then treated to reform barium carbonate therefrom which can be recycled and used again.
Barium carbonate is a white powder. It is insoluble in water and soluble in most acids, with the exception of sulfuric acid.It has a specific gravity of 4.275. It is toxic by ingestion.
