Tungsten Trioxide Notes from Lanthanum Tungsten Electrode Preparation Material

Tungsten trioxide is one of the materials for lanthanum tungsten electrode preparation, when using it for preparing electrodes, then you should pay attention to the following precautions:

(1) The presence of dust should be avoided.
(2) The process should be operated in a closed shop, and the local exhaust ventilation should be carried out to prevent dispersion of dust into the air in workshop.

(4) All operators should wear rubber acid resistance suit, wearing self-absorption filter respirators, chemical safety goggles and rubber gloves and other protective equipment.
(5) The contact between tungsten trioxide and bromine pentfluoride or chlorine trifluoride should be avoided.
(6) Equipped with spill response equipment.
(7) Empty containers where may remain hazardous materials.
(8) Tungsten trioxide should be stored in cool and ventilated coffers and away from fire, heat and direct sunlight.
