Carbonate of Potash Fertilizers K2CO3, HS Code 28364000 Potassium
Carbonate for Agricultural Use
1. Potassium Carbonate K2CO3 Introduction
Potassium carbonate is a inorganic compound substance with chemical
formula K2CO3 and molecular weight of 138.206. It is a white
crystalline powder with a density of 2.428g/cm3 and a melting point
of 891 ℃. It is easily soluble in water, and the aqueous solution
is alkaline. It is insoluble in ethanol. Potassium carbonate has
strong hygroscopicity. When exposed to the air, it can absorb
carbon dioxide and water, which can be converted into potassium
bicarbonate. We have exported potassium carbonate to mainly
countries such as Mexico, Kazakhstan, Egypt, etc.

3. Potassium Carbonate K2CO3 Applications
Potassium carbonate is a versatile chemical substance, whose main
uses include:
1. Potassium carbonate used in agricultural industry
As a potassium fertilizer, potassium carbonate provides plants with
essential potassium elements, which play a crucial role in nutrient
absorption, biochemical metabolism, and adaptability to the
environment. Potassium carbonate fertilizer also has the
characteristic of good water solubility, which can quickly provide
plants with the necessary potassium element and release carbon
dioxide (CO2), enhancing crop photosynthesis.
2. Potassium carbonate used in glass Industry
At high temperatures, glass is prone to softening and deformation.
Potassium carbonate can increase the softening temperature of
glass, giving it better thermal resistance. This is because
potassium carbonate can decompose at high temperatures, producing
CO2 and K2O, which can form more stable compounds with SiO2 and
other oxides, thereby increasing the melting point and softening
temperature of the glass.
3. Potassium carbonate used in glaze industry
Potassium carbonate can lower the melting point of glaze, promote
its melting and flow, make the glaze smoother and more delicate,
thereby improving the quality of the glaze. In addition, potassium
carbonate can also reduce the shrinkage rate and cracking of glaze,
increase the strength and toughness of the glaze layer.
4. Other uses: Potassium carbonate is also used as a gas adsorbent, dry powder
fire extinguishing agent, rubber anti-aging agent, and has
applications in removing carbon dioxide from fertilizer synthesis
gas.
4. Potassium Carbonate K2CO3 Functions in Agricultural Use
The main uses of potassium carbonate K2CO3 in agriculture include
promoting plant photosynthesis, enhancing stress resistance,
improving soil structure, and increasing crop yield and quality.
Potassium carbonate, as a potassium fertilizer, can promote
photosynthesis in plants, improve the efficiency of light energy
utilization, and provide more energy for plant growth. In addition,
potassium also plays an important role in enhancing crop stress
resistance, helping plants resist adverse environmental conditions
such as drought, high temperature, low temperature, pests and
diseases.
Potassium carbonate K2CO3 can also improve soil structure. Long
term application of chemical fertilizers can lead to soil
compaction, affecting aeration and water retention performance. The
potassium ions in potassium carbonate can interact with soil
components, improve soil structure, enhance porosity and aeration
and water retention capacity, and create favorable conditions for
plant root growth.
The application effect of potassium carbonate K2CO3 is significant
on specific crops. For crops that prefer potassium fertilizer, such
as potatoes, sweet potatoes, tobacco, and fruits, adding an
appropriate amount of potassium carbonate can significantly improve
yield and quality. For example, the application of potassium
carbonate can increase the tuber size and starch content of
potatoes, improving their overall quality.
