The solubility of oxides and other ceramic powders depends on what the solution and solvent should be. Temperature is also important. For example one definition of glass says that it is solid solution of natrium oxide, kalium oxide and silicium oxide. many kinds of steel are similarly defined as "interstitial solid solution of carbon in alpha-iron", etc.
As for the solubility of metal oxides in water, it is close to zero. The same for alcohols, ethers, alkanes, etc. The usual way of getting metal oxides into liquids is to mix suspension so fine that the powder will be hard to separate due to the brownian motion and such. Today you may order nano-powder as well.
Now to the point why somebody asked this: 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 (forgot the name). 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.
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.

add sulfuric acid
Endothermic substances.
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.
Cerium hasn't odor.
There are many different types of abrasives that may be used to polish rocks, from diamond powder to aluminum oxide, cerium oxide, etc.
Cerium was not known by alchemists.
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.
Definitely NOE-FERROUS. The word 'ferrous/ferric' is the Latin based adjective for IRON. (Ferrum). Since there is no iron present in cerium oxide then it is non-ferrous.
nitrous oxide : lower solubility halothane : higher solubility
1.cerium oxide is used as a glass-polishing agent 2. in stainless steel it is used as a precipitation agent

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.
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 sulfate is a very strange compound; increasing the temperature the solubility decrease.
Perhaps you mean the solubility of substances in water. Most solids have increasing solubility in water with increase in temperature, but certainly not all of them. Some solids e.g. Cerium Sulphate have decreased solubility in water at higher temperatures, while some solids show increasing solubility up to a certain temperature, above which the solubility decreases, such as Sodium Sulphate. The solubility of common salt, Sodium Chloride, is almost unaffected by temperature. Gases generally have lower solubility in water at higher temperatures.
