 Thermal Expansion

  The formula used to calculate  thermal expansion coefficient 

 for metal  halides and oxides is given as:

α≈ 0.038/ Mp   - 7.0* 10^-6 K^-1

 Now Mp of MoO2= 1373 as reported in ( Wikipedia) Molybdenum (IV)oxide

α≈ 0.038/ Mp   - 7.0* 10^-6 K^-1

 at 20C

2.76766*10^-5 -7*10^-6 K-1

27.6766*10-6 – 7.*10-6 K^-1

 20. 6766 .*10^-6 K^-1
