Cobalt Aluminate powder is a compound powder with spinel structure, bright colour (often blue), good chemical stability, high temperature resistance and optical properties, which has important applications in the fields of pigments, ceramics and optical materials.
VIAMTERIAL supplies Cobalt Aluminate powder, our powder has the features of high purity, uniform particle size, good flowability, good compaction, stable chemical properties, etc. We also support small batch packing and ordering. We have a professional technical research and development team, accept product customisation and experimentation, please contact us.
Molecular Formula: CoAl₂O₄
Molecular weight: about 176.89
Appearance: usually blue powder, bright and uniform colour
Density: about 4.37 g/cm³.
Melting point: about 1900 – 2000℃.
Crystal structure: It belongs to the spinel structure, in which cobalt ions (Co²⁺) and aluminium ions (Al³⁺) are orderly distributed in the cubic lattice made up of oxygen ions (O²-), and this structure endows it with a good chemical stability and physical properties such as optics.
Pigment field: Cobalt Aluminate powder is widely used as a pigment for ceramics, glass and other materials due to its bright and stable blue hue, which gives the products a long-lasting and beautiful decorative effect and meets the needs of artistic creation and industrial production.
Ceramic field: In the ceramic industry, CoAl₂O₄ powder is used as an important additive to enhance the hardness, abrasion resistance and high-temperature resistance of ceramics, and at the same time, give ceramics a unique colour and luster, which expands its application in high-end tableware and architectural decorative ceramics.
Optical materials: Cobalt Aluminate powder is used in the preparation of luminescent materials, optical filters and other optical devices due to its special optical properties, such as the absorption and emission characteristics of specific wavelengths of light, helping to improve the performance and functional diversity of optical instruments.
The quality control of each batch of products is carried out throughout the whole process of raw material procurement, production and processing, testing and inspection, and packaging, strictly following international standards and industry norms. We have advanced testing equipment, professional QC team and strict quality control system to ensure product quality.
Cobalt Aluminate powders are packed in double vacuum bags or double vacuum bottles and packed in cartons.
Cobalt Aluminate powders should be stored in a dry, cool, well-ventilated environment, tightly sealed, protected from moisture, acidic or alkaline substances, away from ignition sources and strong oxidising agents, and stored in accordance with the regulations governing the storage of inorganic powders.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
