Lithium carbonate wet material and dry material mainly in the water content, physical phase composition, particle size distribution, impurity content and other aspects of the differences.
1. Water content: lithium carbonate wet material contains more water, generally more than 10%, while the water content of lithium carbonate dry material is lower, generally less than 5%.
2. Physical composition: lithium carbonate wet material and dry material in the physical composition is also different. Lithium carbonate wet material is mainly made from lithium pyroxene concentrate after high temperature melting, acidification, precipitation, dehydration and other processes, while lithium carbonate dry material is made from low-grade lithium ore, lithium brine or recycled materials after a certain treatment process.
3. Particle size distribution: the particle size distribution of lithium carbonate wet material is relatively narrow, generally 0.1~20μm, while the particle size distribution of lithium carbonate dry material is relatively wide, generally between 1~30μm.
4. Impurity content: lithium carbonate wet material in the impurity content is high, such as calcium, magnesium, iron and other elements, need to go through a certain impurity removal process in order to achieve the standard of battery-grade lithium carbonate. While the impurity content of lithium carbonate dry material is relatively low, after appropriate processing can meet the requirements of battery-grade lithium carbonate.
In general, lithium carbonate wet and dry materials in a number of aspects of the differences, the specific choice of which product should be based on the actual needs and uses to decide.
Sodium sulfate wet and dry materials differ in water content, phase composition, particle size distribution and purity.
1. Water content: Sodium sulfate wet material contains more water, usually more than 10%, while the water content of sodium sulfate dry material is lower, usually less than 5%.
2. Physical composition: Sodium sulfate wet material and dry material are also different in physical composition. Sodium sulphate wet material is usually made of natural minerals or industrial by-products after processing, while sodium sulphate dry material is made of high-purity, fine-grained anhydrous material.
3. Particle size distribution: the particle size distribution of sodium sulfate wet material is relatively wide, while the particle size distribution of sodium sulfate dry material is relatively narrow.
4. Purity: the purity of sodium sulfate wet material is relatively low, containing more impurities, which need to be purified to achieve the high purity requirements. On the other hand, the purity of sodium sulfate dry material is higher, the content of impurities is lower, and it can be directly used for various industrial purposes.
Overall, there are differences between wet and dry sodium sulfate in many aspects, the specific choice of which product should be based on the actual needs and uses to decide.
