Description of potassium sulfate
Name: potassium sulfate, agricultural grade, industrial grade, water-soluble
Molecular formula: K2SO4
Molecular weight: 174.26
Characteristics: colorless or white crystal, particle or powder. Odorless. Bitter taste. Hard quality. Stable in air. 1g is soluble in 8.3ml water, 4ml boiling water and insoluble in ethanol. Ammonium sulfate can increase its solubility in water, but it is almost insoluble in saturated solution of ammonium sulfate. The aqueous solution is neutral with a pH of about 7. The relative density is 2.66. Melting point 1067 ℃.
Application:
1. Applicable to all crops and fruit industry.
2. It can be used as a raw material for compound fertilizer production;
3. Used as medicine (releasing agent), and used in alum, glass and potassium carbonate.
Capacity: 10,000.00~100,000.00tons/Year
The Potassium Sulfate Production Line Equipment is for the Potassium Sulfate produced from Raw material Potassium Chloride KCL and Sulfuric Acid H2SO4 Reaction in Mannheim Furnace. The Main product Potassium Sulfate, By-product it is Hydrochloric acid.
Enhanced Crop Yield and Quality:
Potassium sulfate serves as a highly effective fertilizer, promoting robust plant growth and enhancing crop yield and quality. Its balanced nutrient composition ensures optimal development of various crops, leading to improved harvests with better flavor, texture, and nutritional value. Moreover, its water-soluble nature enables rapid absorption by plants, facilitating efficient utilization of potassium, a vital macronutrient essential for overall plant health and stress resistance.

FAQ：
What are the main characteristics of potassium sulfate?
Potassium sulfate, whether agricultural or industrial grade, typically appears as colorless or white crystals, particles, or powder. It possesses a bitter taste, but is odorless and hard in quality. It is stable in air, soluble in water, with approximately 1g dissolving in 8.3ml of water at room temperature. However, it is insoluble in ethanol and exhibits increased solubility in the presence of ammonium sulfate. Its aqueous solution is neutral with a pH around 7, and it has a relative density of 2.66. Additionally, it has a high melting point of 1067°C.
What are the applications of potassium sulfate?
Potassium sulfate finds wide applications across various industries:
It is suitable for all crops and the fruit industry, serving as a vital nutrient.
It serves as a raw material in compound fertilizer production.
In the medical field, it acts as a releasing agent.
It is also utilized in the production of alum, glass, and potassium carbonate.
How is potassium sulfate manufactured?
Potassium sulfate is typically manufactured through the reaction between potassium chloride (KCl) and sulfuric acid (H2SO4) in a process known as the Mannheim Furnace method. This reaction yields potassium sulfate as the main product and hydrochloric acid as a by-product. The production line equipment includes facilities for handling raw materials, reaction vessels (such as Mannheim Furnaces), and processes for crystallization and drying to obtain the final product.
What is the molecular formula and weight of potassium sulfate?
The molecular formula of potassium sulfate is K2SO4, indicating that each molecule contains two potassium (K) atoms, one sulfur (S) atom, and four oxygen (O) atoms. The molecular weight of potassium sulfate is calculated as 174.26 g/mol.
What is the solubility of potassium sulfate in water and ethanol?
Potassium sulfate demonstrates limited solubility characteristics. Approximately 1g of potassium sulfate can dissolve in 8.3ml of water at room temperature, and 4ml in boiling water. However, it is insoluble in ethanol. The presence of ammonium sulfate can enhance its solubility in water, but it remains almost insoluble in a saturated solution of ammonium sulfate.
What is the production capacity of potassium sulfate manufacturing plants?
Potassium sulfate manufacturing plants typically have a production capacity ranging from 10,000 to 100,000 tons per year. This capacity can vary depending on factors such as plant size, technological efficiency, and market demand for potassium sulfate products.
