♦ 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.

Potassium Carbonate Manufacturers Improve Ion Exchange Process Measures
In addition to a large number of glass and color television tube glass shell, as an important carbonate variety, the application of potassium carbonate has been extended to medicine, chemical dyes, inks and welding rod and other industries.Potassium carbonate manufacturers recycle ammonia ions, according to the principle of chemical balance, the more ammonia ions in the ion exchange process relative to the amount of potassium ions, the higher the utilization rate of potassium ions.However, considering the economic and operational factors in the actual production, the ratio of potassium ion and ammonia ion selected by potassium carbonate manufacturers should be controlled within a certain amount, about 1:1.29. Therefore, a large amount of ammonia ion is not used in the exchange solution, which results in the waste of raw materials.potassium carbonate manufacturers use mixture can produce more than 13% of the exchange liquid, so can reduce the steam consumption of evaporation process and also to make full use of the ammonium carbonate solution, in reducing the costs of raw materials and ammonium chloride wastewater pollutant emissions, has the very good comprehensive benefits.

The Introduction of Potassium Nitrate KNO3
The Introduction of Potassium Nitrate KNO3 FertilizerPotassium nitrate CAS7757-79-1, EINECS 231-818-8, MF KNO3. It is a chlorine-free nitrogen-potassium compound fertilizer with high solubility. Its effective components nitrogen and potassium can be quickly absorbed by crops without chemical residues. As a fertilizer, it is suitable for vegetables, fruits and flowers, and some chlorine-sensitive crops (such as potatoes, strawberries, beans, cabbage, lettuce, peanuts, carrots, onions, blueberries, tobacco, apricots, grapefruit, avocados, etc.). Potassium nitrate is a strong oxidant, which can cause combustion and explosion in contact with organic matter. Therefore, potassium nitrate should be stored in a cool and dry place, away from fire and heat sources. Do not store and transport it with reducing agents, acids, combustible materials, and metal powders. Shanghai Yixin Chemical Co., Ltd. has more than 20 years of potassium nitrate sales experience. Our products have been exported to more than 20 countries in Southeast Asia, Africa and America.

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.
