Standard ceramic disc capacitors are constructed from two metallic electrodes separated by a very thin ceramic disc (serving as the dielectric) inside of a protective coating such as epoxy or other resin. The ceramic disc is produced from finely ground powders sintered at extremely high temperatures.

What is crystalline ceramics?
Crystalline ceramic materials are not amenable to a great range of processing. Methods for dealing with them tend to fall into one of two categories -- either make the ceramic in the desired shape, by reaction in situ, or by "forming" powders into the desired shape, and then sintering to form a solid body. Ceramic forming techniques include shaping by hand (sometimes including a rotation process called "throwing"), slip casting, tape casting (used for making very thin ceramic capacitors, e.g.), injection molding, dry pressing, and other variations. Details of these processes are described in the two books listed below. A few methods use a hybrid between the two approaches.
How does a glaze change the properties of a ceramic?
potters can cover a ceramic with a thin layer of silicon dioxide and heat it again. This process forms a glassy waterproof coating called a glaze.
Are an example of a ceramics?
the examples of ceramic materials are: 1. ceramic art 2. ceramic 3. ceramic classfication 4. ceramic wall 5. ceramic material 6. ceramic man made
Ceramic chipped cup or chipped ceramic cup?

What has bigger mass ceramic or marble?
well its ceramic
What is the difference between monolithic ceramic and mutilayer ceramic capacitors?
Ceramic Multilayer vs Monolithic CapacitorBoth multilayer and monolithic capacitors have multiple layers. The main difference between the two is the manufacturing process. Monolithic capacitors have a paste of ceramic material applied between the conductive layers. After this paste is applied the capacitors are then baked. Multilayer capacitors have the ceramic material sprayed onto the conductive layers. This generally means that monolithic capacitors can't go as high in capacitance because the amount of layers is limited due to their manufacturing process.
Whether film capacitors can be replaced with ceramic or mica capacitor?
Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. However, mica capacitors can be replaced with ceramic capacitors in general.
Are polyester capacitors better than ceramic disk capacitors?
Polyster ones won't wrinkle.
What is an unpolarized capacitor?
A capacitor that does not have a designated + and - side. Electrolytic capacitors are usually polarized. Ceramic capacitors are not.
Difference between ceramic and electrolytic capacitors?
In ceramic capacitors the dielectric is a thin layer of ceramic and both plates are metal foil. These capacitors are unpolarized. These capacitors have negligible internal inductance or resistance.In electrolytic capacitors the dielectric is an ultra thin layer of corrosion on the surface of a metal foil plate and the other plate is an electrolyte paste. These capacitors are polarized and if connected backwards are likely to explode. These capacitors have significant internal inductance, making them bad filters of noise in the MHz range and above which requires ceramic capacitors.
What is use of decoupling capacitor?
to protect a circuit from damaging
What are the different types of capacitors?

What is the functions of ceramic capacitor?
Ceramic capacitors can be used anywhere a capacitor having very low internal parasitic inductance is required. Most commonly they are used as powersupply bypass capacitors. They are also sometimes used for coupling capacitors for HF signal amplifiers.
Modern capacitors which have high capacitance in small size use a dielectric?
Ceramic
How do capacitors classified?
capacitors are classified on the basis of dielectric material used inside it. For example the electrolytic capacitor consist electrolyte as dielectric mica capacitor consist mica as dielectric between plates and ceramic capacitor consist ceramic as dielectric.
How ceramic capacitors can do filtering in replacement of electrolytic capacitors?
Electrolytic capacitors do a very good job of bulk filtering, but they have poor high frequency performance due to distributed inductance. The ceramic capacitor has excellent high frequence response, and will often be used in parallel to the electrolytic to filter out fast rise time step changes in current demand.
Can monolithic capacitors be used as a substitute for ceramic?
ceramic capacitors are usually monolithic. monolithic has more physical stability with a solid electrolyte film capacitors multilayer (paper and tinfoil) dont have as stable a dimension if you are trying to make an RC oscillator monolithic has a stable frequency
