Overview
Potassium molybdate (K2MoO4) is an inorganic compound that serves as a vital source of molybdenum, an essential micronutrient for plants and animals. It is commonly used in agricultural applications to correct molybdenum deficiencies in crops, enhancing nitrogen fixation and overall plant health. In industrial settings, potassium molybdate acts as a corrosion inhibitor and catalyst in chemical processes. Its high solubility and stability make it a preferred choice for various applications, including water treatment and metallurgy.
Physical and Chemical Properties
Potassium molybdate appears as a white crystalline powder with a density of 2.46 g/cm³ and a melting point of 919°C. It is highly soluble in water, forming clear solutions, and is stable under normal conditions. The compound is non-flammable and non-reactive under most circumstances, but it should be handled with care to avoid inhalation or contact with skin and eyes. Its stability and solubility make it suitable for a wide range of applications, from agriculture to industrial processes.
Main Applications
In agriculture, potassium molybdate is primarily used as a micronutrient fertilizer to address molybdenum deficiencies in crops like legumes, which rely on molybdenum for nitrogen fixation. It is often applied as a foliar spray or soil amendment. Industrially, potassium molybdate serves as a corrosion inhibitor in cooling systems and as a catalyst in chemical reactions. It is also used in the production of pigments, ceramics, and other specialty chemicals. Its versatility and effectiveness make it a valuable compound in multiple sectors.
Safety and Storage
Potassium molybdate should be stored in a cool, dry place away from moisture and incompatible substances. Proper ventilation is recommended to prevent dust accumulation, which can pose inhalation risks. Personal protective equipment, such as gloves and goggles, should be worn when handling the compound. In case of contact with skin or eyes, rinse immediately with plenty of water. While it is not highly toxic, prolonged exposure should be avoided to prevent potential health effects.
B2B Procurement Guide
When procuring potassium molybdate, B2B buyers should prioritize suppliers with verified certifications and a track record of quality. Purity levels (typically 99% or higher) should be confirmed to ensure the compound meets application requirements. Bulk purchases often yield cost savings, but storage conditions must be adequate to maintain product integrity. Buyers should also consider logistical factors, such as shipping and handling, to prevent contamination or degradation during transit.
