♦ Description
Sodium fluorosilicate is the byproduct in the production of calcium phosphate or
the production of fluoride salt in aluminum factory.
It generally appears as a white crystalline powder with low solubility in water
(being 1% or less at room temperature), and the water solubility increases slightly
with increasing temperature.
The aqueous solution of sodium fluorosilicate is acidic (pH3). This is due to that
its hydrolysis product contains hydrofluoric acid.
When pH is lower than 3.5-3.55, the hydrolysis reaction is stabilized. When
the pH is equal to 4, the hydrolysis reaction rate is significant. When the pH value is
equal to 8-8.5, the sodium fluorosilicate can be completely hydrolyzed to exhibit as
silica gel and precipitated out.
Therefore, when sodium fluorosilicate is added to the water glass, in addition
to hardening effect of precipitation of silicon dioxide gel caused by the neutralization
of the sodium hydroxide in the solution of water glass, the sodium fluorosilicate
itself is also a source of silica gel.

The Future Development of Barium Carbonate
Barium carbonate is an important inorganic chemical raw material. As an important upstream product, it is widely used in many industrial industries. In recent years, the barium carbonate industry is facing industrial upgrading and changing demand conditions.Based on the current market situation, the primary problem for barium carbonate manufacturers is how to formulate the corresponding industrial development strategy according to the change of industrial environment.Barium carbonate manufacturers should give full play to their advantages of resources and scale, reduce production costs and ensure their cost advantages in the face of changing market environment based on their own natural resources and advanced production technology, so as to occupy a considerable share of the low-end market of barium carbonate industry.Colleagues, barium carbonate manufacturers have been able to produce high-purity barium carbonate through their own technological innovation and cooperation with foreign companies, so as to adapt to market changes better.China is a big country for producing barium carbonate. At present, its output accounts for more than 70% of the world's total output. However, the added value of barium carbonate products is low and resources cannot be effectively utilized.The production of high-purity barium carbonate has always been the development direction of barium carbonate manufacturers in China.Regarding the industrial development of strategic research for barium carbonate manufacturers, its purpose is to grasp the market competition situation, to formulate the correct competition strategy, to promote the stable and sustainable development of barium carbonate manufacturers.

The ion exchange method in potassium carbonate manufacturing
In addition to a large number of tubes for glass and color TV sets, potassium carbonate is an important carbonate variety. The application of potassium carbonate has expanded into various industries such as pharmaceuticals, chemical dyes, inks and welding electrodes.The ion exchange method is an important process for the production of potassium carbonate. It is used by most potassium carbonate manufacturers. The ion exchange method is further improved, and the potassium carbonate manufacturers have improved the ion exchange method.Potassium carbonate manufacturers recycle ammonia ions. According to the principle of chemical equilibrium, the more the amount of ammonia ions in the ion exchange process relative to the amount of potassium ions, the higher the utilization rate of potassium ions. However, in consideration of economic and operational factors in actual production, the ratio of potassium ion and ammonia ion selected by the potassium carbonate manufacturer needs to be controlled within a certain amount, which is about 1:1.29, so there is no large amount of ammonia ion in the exchange liquid. Being used, it also causes waste of raw materials. Potassium carbonate manufacturers need to recycle these ammonia ions, which can achieve good economic benefits. Similarly, the concentration of potassium bicarbonate in the solution should be controlled. The potassium carbonate manufacturer can produce more than 13% of the exchange liquid, which can reduce the steam consumption in the evaporation process and fully carry out the ammonium carbonate solution. The utilization has reduced the cost of raw materials and the emission of pollutants in ammonium chloride wastewater, and has a good comprehensive benefit.Potassium carbonate manufacturers have improved the steam section to remove impurities such as iron ions, which has increased the yield of color TV grade potassium carbonate products to 70%. The potassium carbonate manufacturer improved the evaporation mode and used three-effect evaporation to enhance the carbonization effect.

Global Barium Carbonate Markets
Barium carbonate is a white, odourless and heavy salt of barium with the chemical formula BaCO3. It is widely used as flux in ceramics, as an ingredient in specialty glass and fine glassware, in the treatment of salt brines, etc. According to this latest report “Barium Carbonate Market: Global Industry Trends, Share, Size, Growth, Opportunity and Forecast 2019-2024”, the global barium carbonate market has grown at a CAGR of nearly 7% during 2011-2018 driven by the continuous use of barium carbonate in the production of specialty glass, bricks and tiles. The report further provides a comprehensive insight into the industry including its market breakup by region, market breakup by end-use, value chain analysis, import and export trends, key players and market outlook. The report also gives an in-sight into the manufacturing process of barium carbonate, covering key success and risk factors for manufacturers, detailed process flow, the reactions involved, raw materials and their requirements, etc.The report has segmented the global barium carbonate market on the basis of end-use. Barium carbonate has applications in a wide variety of industries. It is used in the glass manufacturing industry as it increases the refractive index and lustre of the glass. Specialty glass made by using barium carbonate provides radiation shielding in CRT televisions. It is also used in making bricks, clays, photographic paper coatings, hard ferrite magnets, permanent ceramic magnets for loudspeakers and in the removal of sulphate from salt brines before they are fed into electrolytic cells. The report finds that the glass industry accounts for almost half of the total consumption of barium carbonate. It is followed by brick and clay, barium ferrites and photographic paper coating industries.The report has segmented the global barium carbonate market on the basis of major regions. China currently dominates the barium carbonate market accounting for the majority of the total global production. On the basis of import data, Japan represents the largest global importer of barium carbonate followed by the Republic of Korea, Spain, Saudi Arabia and France.
