Product Description
Basic Information
- Chemical Name and Structure: Lithium Carbonate, characterized by the chemical formula Li2CO3, is a remarkable ionic compound. It features a sophisticated structure comprising lithium ions and carbonate ions. The carbonate ion boasts a planar triangular configuration, where the central carbon atom is intimately covalently bonded to three oxygen atoms. In this stable structure, lithium ions are securely bound to the carbonate ion via ionic bonds, creating a robust and reliable compound.
- Appearance and Properties: Lithium carbonate is typically presented as a white powder or striking colorless monoclinic crystals. These unique monoclinic crystals possess a specific crystal structure that holds significant value in optical and crystallographic studies. When found in its powder form, lithium carbonate is fine-textured, completely odorless, and tasteless, enhancing its versatility and ease of use in various applications.
Quality Standards and Specifications
- Purity Requirements: For industrial-grade lithium carbonate, purity levels generally hover between 98% and 99%, making it ideal for uses in sectors like glass and ceramics, where ultra-high purity isn't essential. However, in cutting-edge sectors such as battery production and pharmaceuticals, the demand for extraordinarily high purity lithium carbonate is paramount, often exceeding 99.5% or even higher, ensuring superior product performance and quality.
- Impurity Limitations: Strict guidelines are in place to limit impurity content in lithium carbonate. Typical impurities include metal ions such as sodium (Na), potassium (K), calcium (Ca), and magnesium (Mg), alongside anions like sulfate and chloride. In top-tier lithium carbonate products, these impurities are meticulously controlled to remain at minimal levels. For instance, sodium content should not surpass 0.05%, while sulfate content should be restricted to a maximum of 0.1%.
Battery Industry: Lithium carbonate serves as a pivotal raw material in crafting cathode materials for lithium-ion batteries. When formulating cathode materials such as lithium cobalt oxide and lithium iron phosphate, lithium carbonate is indispensable as a source of lithium. These cathode materials are integral to batteries used in a plethora of electronic devices and electric vehicles, ensuring high energy density and superior cycle performance.
Medical Field: In the field of medicine, lithium carbonate is primarily harnessed to treat mental ailments, including mania. It effectively modulates neurotransmitter levels within the central nervous system, contributing to mood stabilization. Additionally, in certain drug synthesis processes, lithium carbonate serves as a crucial reagent, participating actively in chemical reactions.
Ceramics and Glass Industry: Within the ceramics domain, lithium carbonate plays a vital role by lowering the sintering temperature, enhancing mechanical properties, and boosting thermal stability. In glass production, the inclusion of lithium carbonate significantly augments chemical stability, enhances strength, and optimizes refractive index, proving indispensable in crafting optical and special-purpose glass.
Metallurgical Industry: In metallurgy, lithium carbonate finds application as an additive during the smelting of non-ferrous metals. For instance, in aluminum electrolysis, adding lithium carbonate can decrease the melting point of the electrolyte and improve its conductivity, thereby significantly enhancing aluminum production efficiency.
