Overview
Calcium vanadate (high purity grade) is an inorganic compound primarily used in industrial applications. It is valued for its stability and catalytic properties, making it essential in chemical manufacturing and material science. The high-purity grade ensures minimal impurities, which is critical for specialized uses such as phosphors and advanced ceramics. This compound is typically synthesized through solid-state reactions or precipitation methods. Its role in metallurgy and pigment production underscores its importance in B2B markets, where quality and consistency are paramount.
Physical and Chemical Properties
Calcium vanadate appears as a white or yellowish crystalline powder with a density of 3.2 g/cm³. It exhibits high thermal stability, with a melting point around 1400°C, and is slightly soluble in water but more soluble in acidic solutions. These properties make it suitable for high-temperature applications and chemical processes. As an oxidizer, it requires careful handling to avoid reactions with reducing agents. Its non-flammable nature reduces fire risks, but proper storage and handling are necessary to prevent dust inhalation or contact with moisture, which could degrade its quality.
Main Applications
The primary use of high-purity calcium vanadate is in catalysts for oxidation reactions, particularly in petroleum refining and chemical synthesis. Its ability to promote selective oxidation makes it valuable in producing specialty chemicals. In ceramics, it serves as a pigment due to its stable color properties under high temperatures. It is also used in phosphors for lighting and display technologies, where purity directly impacts performance. Additionally, it plays a role in metallurgy as a flux or alloying additive.
Safety and Storage
Calcium vanadate requires cautious handling to avoid respiratory or dermal irritation. Personal protective equipment (PPE), including gloves and goggles, is recommended. Workspaces should have adequate ventilation to minimize dust exposure. Storage conditions should be dry and cool, away from incompatible materials like strong acids or reducing agents. Containers must be sealed to prevent moisture absorption. Spills should be cleaned promptly with appropriate measures to avoid environmental contamination.
B2B Procurement Guide
When procuring high-purity calcium vanadate, buyers should prioritize suppliers with certifications (e.g., ISO) and request detailed product specifications, including purity levels (typically ≥98%). Batch testing reports and Safety Data Sheets (SDS) are essential for compliance and risk assessment. Pricing varies based on order volume and purity, with bulk purchases often attracting discounts. Lead times and logistics (e.g., hazardous material shipping) should be clarified. Establishing long-term contracts with reliable suppliers can ensure consistent quality and supply chain stability.
