Molybdenum(VI) oxide is soluble in strong alkaline water, forming molybdates (MoO 4 2−). Molybdates are weaker oxidants than chromates. They tend to form structurally complex oxyanions by condensation at lower pH values, such as [Mo 7 O 24] 6− and [Mo 8 O 26] 4−. Polymolybdates can incorporate other ions, forming polyoxometalates.

Molybdenum oxide may refer to: Molybdenum(IV) oxide (molybdenum dioxide, MoO 2) Molybdenum(VI) oxide (molybdenum trioxide, MoO 3) Other stoichiometric binary ...
Molybdenum dioxide is a constituent of "technical molybdenum trioxide" produced during the industrial processing of MoS 2: [4] [5] 2 MoS 2 + 7 O 2 → 2 MoO 3 + 4 SO 2 MoS 2 + 6 MoO 3 → 7 MoO 2 + 2 SO 2 2 MoO 2 + O 2 → 2 MoO 3. MoO 2 has been reported as catalysing the dehydrogenation of alcohols, [6] the reformation of hydrocarbons [7] and ...

Electrical conductivity of water samples is used as an indicator of how salt-free, ion-free, or impurity-free the sample is; the purer the water, the lower the conductivity (the higher the resistivity). Conductivity measurements in water are often reported as specific conductance, relative to the conductivity of pure water at 25 °C.
The thermal conductivity of a material is a measure of its ability to conduct heat.It is commonly denoted by , , or and is measured in W·m −1 ·K −1.. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity.

Molybdenum bonds to the glass via the intermediate layer of molybdenum(IV) oxide. Due to its low thermal expansion coefficient, matched to glass, molybdenum, like tungsten, is often used for glass-metal bonds especially in conjunction with aluminium-silicate glass. Its high electrical conductivity makes it superior over nickel-cobalt-iron alloys.
