Niobium (V) oxide is used as a single crystal of nickel ruthenate, special optical glass, high frequency and low frequency capacitors and piezoelectric ceramic components. It is also used in the production of various niobium alloys for niobium and special steels. It is a raw material for the preparation of hydrazine and its compounds. Also used as a catalyst, refractory material.
Physicochemical properties of Niobium(V) oxide
Character White powder.
The relative density is 4.47 g/cm3.
Melting point 1485 ° C ± 5 ° C.
It is insoluble in water, hardly soluble in acid, and soluble in molten potassium hydrogen sulfate or alkali metal carbonates or hydroxides.
Solution: do not dissolve in water, in addition to sulfuric acid and hydrofluoric acid, insoluble in other acids.
It turns yellow when heated and turns white after cooling. Decomposed by co-melting with an alkali metal acid sulfate, hydrochloride or hydroxide.
Use of Niobium(V) oxide
Used as a single crystal of nickel phthalate, special optical glass, high frequency and low frequency capacitors and piezoelectric ceramic components. It is also used in the production of various niobium alloys for niobium and special steels. It is a raw material for the preparation of hydrazine and its compounds. Also used as a catalyst, refractory material.
Safety of Niobium(V) oxide
The high-purity Niobium(V) oxide are packed in double-layer polyethylene plastic bottles, each with a net weight of 5kg and tightly sealed. The back jacket polyethylene plastic bag is placed in a hard box and filled with paper dust to prevent cocking. The net weight of each box is 20kg. The industrial products are double-layer polyethylene plastic bags and outer jackets with a net weight of 40kg per drum. Store in a well ventilated, dry place. Do not stack in the open air. The package should be sealed. Protect from rain and packaging when transporting.
In case of fire, use water, sand and fire extinguishers to save. Toxicity and protection: Occupational poisoning has not been documented. Workers who use iridium complexes have a relatively high incidence of upper respiratory tract, which may be related to the effects of separated hydrogen fluoride and fluoroantimonate. The maximum allowable concentration of cerium and its oxide is 10 mg/m3; the fluorine-containing compound is usually calculated as fluorine, i.e., 1 mg/m 3 . To work in an environment with a high dust content, wear a respirator and pay attention to ventilation and dust removal.
