Cobalt oxide Uses

Cobalt(II) Oxide (CAS NO.1307-96-6) is used in pigments for ceramics, glass coloring & decolorization, prepn of cobalt metal catalysts, oxidation catalyst for drying oils, fast drying paints & varnishes, cobalt powder for binder in sintered tungsten carbide, in semiconductors.It alsohas for centuries used as a coloring agent on kiln fired pottery, the earliest examples go back to 12th century German pottery.[6] The additive provides a deep shade of blue named Cobalt blue. The band gap (CoO) is around 2.4 eV.

Cobalt oxide Specification

Cobalt(II) Oxide (CAS NO.1307-96-6) is a olive green, red, gray or black, odorless powder.
First Aid Measures:
Ingestion: Never give anything by mouth to an unconscious person. Get medical aid. Do not induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water. Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.
Inhalation: Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention. May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated.
Skin: May cause skin irritation.Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.May cause eye irritation. Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
Handling and Storage:
Storage: Kepp container tightly closed. Suitable for any general chemical storage area. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
