Vaporization and thermodynamic properties of the PbO-V2O5 system

Thermochemical study of gaseous salts of oxygen-containing acids: XIX. Tin salts

“…The oxides V 4 O 10 , B 2 O 3 , and MoO 3 act as anionforming species in the high-temperature synthesis of gaseous salts [7][8][9]. When gaseous oxides V 4 O 10 , B 2 O 3 , and MoO 3 coexist with gaseous SnO, the corresponding gaseous salts are synthesized [10].…”

“…The SnВ 2 О 4 + ion is a product of SnB 2 O 4 direct ionization, and the SnВO 2 + ion is a product of the dissociative ionization of the SnB 2 O 4 molecule [Eq. (8)]. A long-term evaporation of the mixture and an increase in temperature result in the appearance of SnBO 2 molecules in vapor.…”

“…As a result of ionization of these molecules [Eq. (8)] and of simultaneous reaction (8) the values of SnВO 2 + ionic currents are summed up. The Sn 2 В 2 O 5 + ion is a product of the Sn 2 В 2 О 5 direct ionization, and the Sn 2 В 2 O 3 + is a product of the Sn 2 В 2 О 5 molecule dissociative ionization [Eq.…”

Comparative studies in subsolidus areas of ternary oxide systems PbO–V2O5–In2O3 and PbO–V2O5–Fe2O3

“…It is also known that lead(II) oxide sublimes before melting. This process, according to the data given in [17], was observed in temperature range 627-877°C.…”

Thermodynamic properties of the gaseous lead phosphates

“…The AEs of thePbPO 3 ions[14,15,27]. Thus the vapor composition over the Pb(PO 3 ) 2 at the temperature range of 1000-1200 K is a mixture of P 4 O 10 , PO 2 , Pb, PbO, PbPO 3 , and PbP 2 O 6 .The partial vapor pressures of the gaseous species were measured by the ion current comparison method.…”
