The cerium oxide is inert. The point when it becomes interesting is at higher temperatures when it can oxidize carbon for example at temperature much lower than the carbon will usually burn. Another useful property is that it will reduce nitrogen oxides and take the oxygen to form its ceric oxide state. This is used in car catalysts due to good efficiency and favorable price. Yet another use - which can be derived from wikipedia information already is chemical reaction with laughing gas - N2O to form really strong, orange oxidiser (NH4)2Ce(NO3)6 - ceric ammonium nitrate. I plan to test it in a rocket engine fuel soon.
Just to note - many combustion processes, whether in furnace, cars, rockets can not be enhanced, taken more power from them, because of the limited speed of reaction. That is where catalysts take place. Ceric oxide can act as a catalyst. When reacted with certain nitrous oxides it can take form of another chemical composition which acts as a strong oxidiser potentially increasing the speed of the reaction even further.
It is said that the east German racers used ceric oxide fuel additive to improve combustion of their vehicles on some races and thus cheated, but closer information on their setup is hard to find. In general ceric oxide will improve combustion if the combustion has tendency to form carbon particles, like in diesel engines or race engines with high fuel:air ratio.
The maximum surface area of ceric oxide nano-powders ranges from 35-70 square meters per gram of the powder. Ordinary polishing powders do not have such large surface area since they are aimed for polishing, not as a catalyst.

Cerium oxide is non ferrous, as it does not contain any iron.
Cerium Oxide is most commonly used for glass polishing. The Cerium Oxide makes the glass softer therefore making it much easier to polish. It is also used in catalytic converters.
- Cerium is is used in mixtures for gas mantles- Cerium is used to prepare pyrophoric allysThe most important compounds are cerium sulfate (used in cerimetry) and cerium oxide (used as abrasive, etc.)
add sulfuric acid
1.cerium oxide is used as a glass-polishing agent 2. in stainless steel it is used as a precipitation agent
Nitrous oxide causes more of the fuel to burn, resulting in more power.
The Cerium ion can hold a charge of +2, +3 and +4. The +2 state is rare can only seen with elements H2, I2, and S. Often seen in the form of Cerium(IV) oxide.
There are many different polishes, including diamond, aluminum oxide, cerium oxide, etc.
oxide is not. But nitrous oxide is!
You can use it on glass or metal to get rid of scratches. Cerium oxide can remove moderate scratches but not too deep. You have to mix it to the right amount, and apply it with a drill bob or buffer. Once you are satisfied with your scratch removal, clean your car to remove splatter.
Hematite is a soft stone, and there are many different polishes out there. Very fine diamond, aluminum oxide, and cerium oxide are a few.
Cerium has many different uses, many most likely in your own home. Cerium oxide is used to color glass for lamps and stained glass, and is also used in lighters to start the fire. It is used in porcelain and glass cleaning powders, so Windex probably contains some cerium. Any porcelain knick knacks you have may contain cerium, too. So you see, cerium has many different uses.It is more commonly used in house hold cleaning agents such as Windex. Cerium has to be artificiallythat is not commonly found in nature.
There are many different types of abrasives that may be used to polish rocks, from diamond powder to aluminum oxide, cerium oxide, etc.
A tumbler, diamond-wheel cabochon machine, or facetting machine can be used to polish hematite. Very fine diamond, tin oxide, or cerium oxide are different polishes that can be used.
Crucibles are used in laboratories for melting or for reactions at high temperature. The materials are very different: aluminum oxide, magnesium oxide, porcelain, stainless steel, nickel, zirconium, platinum and platinum alloys, graphite, quartz, thorium oxide, beryllium oxide, cerium sulphides, etc.
Cerium is not dangerous.
Cerium is soft
burning of fuel is a chemical reaction which makes the fuel to combine with oxygen thus forming an oxide
Magnesium oxide was used as an antacid and laxative.
Cerium is a inner transition metal
Cerium is an inner transition metal.
Cerium was not known by alchemists.
it can be the good fuel for photosynthesis but not for vehicles.
Metals: platinum, platinum alloys (with Rh, Au, Ir), Pt-zirconia stabilized, nickel, zirconium, inconel 601, tantalum, molybdenum, etc. Ceramics: porcelain, mullite, aluminum oxide, aluminum nitride, zirconium oxide (with 10 % yttrium oxide), magnesium oxide, beryllium oxide, cerium sulphide, silica, etc. Vitrous graphite
