Specification
The Terbium trifluoride ,its cas register number is 13708-63-9.It also can be called as Terbium(III) fluoride and the IUPAC name about this chemicals is Trifluoroterbium .It belongs to the following product categories, such as Catalysis and Inorganic Chemistry, Chemical Synthesis, Crystal Grade Inorganics, Salts, Terbium Salts, TerbiumMetal and Ceramic Science .Following are the chemical properties about this chemicals:(1)Enthalpy of Vaporization: 25.54 kJ/mol ;(2)Vapour Pressure: 922 mmHg at 25°C .
The Terbium trifluoride is a powder, it is sensitive to hygroscopic and insoluble in water.This chemicals is dangerous, because it is harmful by inhalation, in contact with skin and if swallowed and irritating to eyes, respiratory system and skin. In the using process, you need to wear suitable protective clothing and gloves and in case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Except these safty informations, there are also exist other data like WGK Germany about is 3,RTECS is WY9367500, Hazard Note is Toxic ,HazardClass is 6.1 and PackingGroup is III.
If you want to sotre this chemicals, please keep containers tightly sealed, and store in cool, dry place in tighely closed containers, also ensure good ventilation/exhaustion at the workplace.Follow are some neasures about first aid, after inhalation, sopply fresh air, if required,provide artificial respiration and keep patient warm.After skin contact, seek immediate medical advice and instantly wash with water, soap and rinse thoroughly.
This chemicals can be described computed from structure:
(1)Canonical SMILES: F[Tb](F)F
(2)InChI: InChI=1S/3FH.Tb/h3*1H;/q;;;+3/p-3
(3)InChIKey: LKNRQYTYDPPUOX-UHFFFAOYSA-K
