Chromium Oxide (Cr2O3), also known by its CAS number 1308-38-9, is a fundamental inorganic compound that plays a critical role across numerous industrial sectors. Its characteristic vibrant green color, coupled with remarkable stability and resistance to heat and chemicals, makes it a highly sought-after material. For businesses seeking to procure this essential compound, understanding its properties and the nuances of sourcing from China is paramount. This guide is designed for procurement managers, R&D scientists, and formulators looking to make informed purchasing decisions.

Understanding Chromium Oxide: Properties and Advantages

At its core, Chromium Oxide is an inorganic compound prized for its stability. Its chemical formula, Cr2O3, indicates a compound with a high melting point (around 2435°C) and boiling point (around 4000°C), rendering it exceptionally resistant to thermal degradation. It is virtually insoluble in water, acids, and alcohols, further enhancing its durability in challenging environments. This insolubility, combined with its physical hardness, makes it an excellent candidate for applications requiring wear resistance and colorfastness.

The primary appeal of Chromium Oxide lies in its consistent green hue. As a pigment, it's used extensively in paints, inks, glasses, and ceramic glazes. The intensity of the green can be adjusted by varying the concentration or by combining it with other metal oxides. For instance, small additions of cobalt or copper can modify the shade, while higher concentrations might lead to a black appearance. Beyond its pigmentary uses, its refractory nature makes it indispensable in lining high-temperature furnaces and kilns, particularly in the glass and fiberglass industries.

Furthermore, Chromium Oxide serves as a valuable catalyst in various organic and inorganic chemical syntheses. Its applications also extend to metal polishing, where its abrasive qualities help achieve a smooth, refined finish on metal and optical surfaces. The compound’s chemical inertness and stability make it a reliable choice for formulators and manufacturers across diverse fields.

Navigating the Chinese Market: Finding a Reliable Chromium Oxide Manufacturer and Supplier

When sourcing Chromium Oxide from China, it is crucial to partner with a reputable manufacturer and supplier. The Chinese chemical market offers a wide range of options, and selecting the right one can significantly impact product quality, pricing, and supply chain reliability.

For procurement managers, key considerations include:

  • Product Purity and Specifications: Ensure the supplier can consistently deliver Chromium Oxide meeting your required purity levels (e.g., 99% or higher) and particle size specifications. Request Certificates of Analysis (COA) for each batch.
  • Manufacturing Capabilities: A manufacturer with robust production facilities and stringent quality control processes is essential. Look for suppliers who adhere to international quality standards.
  • Pricing and Minimum Order Quantities (MOQ): Compare pricing across different suppliers, but always balance cost with quality and reliability. Understand their MOQs for bulk purchases to ensure they align with your production volumes.
  • Supply Chain Reliability and Lead Times: A stable supply chain is critical. Inquire about their production capacity, inventory management, and typical lead times for both domestic and international shipments.
  • Technical Support and Customer Service: A responsive supplier who can offer technical assistance regarding product applications, handling, and regulatory compliance can be invaluable.
