Physical and chemical properties
physical property
Appearance and characteristics: Dark gray powder or crystal.
Melting point (℃): 400 (decomposition)
Relative density (water=1): 3.76
Solubility: insoluble in water.
Chemical property
Slowly decompose at 400 ℃ and completely dehydrogenate in vacuum at 600-800 ℃. High chemical stability, does not interact with air and water, but easily interacts with strong oxidants. The goods are screened and supplied in different particle sizes.
Function and Application
It can be used as a getter in the electro vacuum process, as a hydrogen source in the manufacture of foam metal, as a source of high-purity hydrogen, and also used to supply titanium to alloy powder in metal ceramic sealing and powder metallurgy.
Precautions for use
Hazard Overview
Health hazards: Inhalation and ingestion are harmful. Animal experiments have shown that long-term exposure may lead to pulmonary fibrosis and affect lung function. Explosive hazard: Toxic.
Emergency measures
Skin contact: Remove contaminated clothing and rinse with plenty of running water. Eye contact: Lift the eyelids and rinse with flowing water or saline solution. Seek medical attention. Inhalation: Quickly leave the scene and move to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, administer oxygen. If breathing stops, immediately perform artificial respiration. Seek medical attention. Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.
Fire protection measures
Hazardous characteristics: Flammable in the presence of open flames and high heat. Can react strongly with oxidants. Powder and air can form explosive mixtures. Heating or contact with moisture or acids releases heat and hydrogen gas, causing combustion and explosion. Harmful combustion products: titanium oxide, hydrogen gas, titanium, water. Fire extinguishing method: Firefighters must wear gas masks and full body firefighting suits, and extinguish the fire in the upwind direction. Fire extinguishing agents: dry powder, carbon dioxide, sand. It is forbidden to use water and foam to extinguish the fire.
Emergency response to leakage
Emergency response: Isolate the contaminated area and restrict access. Cut off the fire source. It is recommended that emergency personnel wear dust masks and anti-static work clothes. Do not come into direct contact with the leaked material. Minor leakage: Avoid dust and collect in a sealed container with a clean shovel. Massive leakage: Collect and recycle or transport to waste disposal sites for disposal.
Handling and Storage
Precautions for operation: Closed operation, local exhaust. Prevent dust from being released into the workshop air. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety goggles, anti toxic work clothes, and latex gloves. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid generating dust. Avoid contact with oxidants and acids. Pay special attention to avoiding contact with water. Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances. Storage precautions: Store in a cool, dry, and well ventilated warehouse. Stay away from sources of fire and heat. Protect from direct sunlight. Maintain relative humidity below 75%. Sealed packaging. It should be stored separately from oxidants, acids, etc., and avoid mixing storage. Adopt explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with suitable materials to contain leaked materials. The current market price is 500.00 yuan per kilogram
Preparation
Titanium dioxide can be directly reacted with hydrogen or reduced with calcium hydride in hydrogen gas.
