How is zirconia (ZrO2) obtained?
Is it mined? Is it mined from Zirconium and then converted into zirconia? If so, how does it get converted to zirconia?
Homework Answers
Zirconia is produced by calcining (calcination at 900 °C) zirconium compounds. Ore baddeleyite contains relatively high, pure concentrations of zirconium oxide and is extracted from sand and gravel deposits. Zirconia is a polymorphic material occurring in three temperature-dependent forms: monoclinic or baddeleyte, tetragonal and cubic. monoclinic is stable phase of all of these three forms.
Zr + O2 --> ZrO2.

"Native," or elemental copper can be found in nature, but most copper is mined as oxide or sulfide minerals. Chalcopyrite (CuFeS2) is one copper mineral that can be converted to elemental copper in a series of chemical steps. Reacting chalcopyrite with oxygen at high temperature produces a mixture of copper sulfide and iron oxide. The iron oxide is separated from CuS by reaction with sand (SiO2). CuS is converted to Cu2S in the process and the Cu2S is burned in...

30% of the energy produced from a nuclear power plant is converted to 1000 MW of electrical energy. The remaining 70% of the energy from this plant is converted to heat waste. 20% of the heat waste is released out of the smokestack. 80% of the heat waste is taken away by cooling water that is drawn from a nearby river. Specific heat of water = 4.184 kJ/kgºC a) How much of the heat waste is taken away by the...
