Overview
Diopside powder is derived from diopside, a mineral belonging to the pyroxene group. It is primarily composed of calcium, magnesium, and silicate, making it a valuable raw material in industrial applications. The powder form is achieved through mechanical grinding and sieving to achieve the desired particle size. Due to its thermal stability and fluxing properties, diopside powder is extensively used in ceramics and glass manufacturing. It acts as a flux, lowering the melting point of mixtures and improving the quality of the final product. Additionally, its low thermal expansion coefficient makes it suitable for high-temperature applications.
Physical and Chemical Properties
Diopside powder is characterized by its white to light green color and fine, granular texture. It has a density of 3.2-3.4 g/cm³ and a melting point of 1391°C, making it highly resistant to thermal degradation. The powder is insoluble in water and most organic solvents, ensuring stability in various industrial processes. Key chemical properties include its role as a fluxing agent, which reduces the energy required for melting in ceramic and glass production. Its low thermal expansion coefficient minimizes stress in high-temperature applications, making it ideal for refractory materials and welding rods.
Main Applications
Diopside powder is widely used in the ceramics industry as a flux to lower firing temperatures and improve glaze quality. In glass manufacturing, it enhances the durability and clarity of glass products. The metallurgical industry utilizes it as a slag conditioner and in welding rod coatings. Other applications include its use in construction materials, such as tiles and sanitaryware, due to its thermal and chemical resistance. It is also employed in the production of synthetic gemstones and as a filler in plastics and rubber to improve mechanical properties.
Safety and Storage
Handling diopside powder requires precautions to avoid inhalation of dust, which can irritate the respiratory system. Workers should use protective equipment, such as masks and gloves, and ensure adequate ventilation in the workspace. Storage conditions should be dry and cool to prevent moisture absorption, which can affect the powder's performance. It is recommended to keep the powder in sealed containers and away from incompatible substances, such as strong acids or oxidizing agents.
B2B Procurement Guide
When procuring diopside powder, buyers should prioritize suppliers with certifications for quality and environmental standards. Key specifications to verify include purity (typically 95-99%), particle size distribution (usually 200-400 mesh), and absence of impurities like iron or heavy metals. Price negotiation should consider bulk purchase discounts, with reference prices ranging from $200 to $500 per ton. Buyers should also evaluate logistics and storage capabilities to ensure the powder remains in optimal condition upon delivery.
