In summary, Barium Titanate is a common ceramic dielectric material that is commercially available in powdered form. This substance is used to create capacitors with high K values, but it is not clear how it is turned into a dielectric material for larger capacitors. It may be achieved through sintering or suspension in a binding polymer. However, if sintering is the method used, it may limit the size of the plates and affect its application in very large capacitors, such as those used in electric vehicles. Overall, more information is needed to fully understand the production process and potential limitations.

Hello all,

I know Barium Titanate is a common ceramic dielectric material. However, the methods of production seems to result in a powdered form of this substance, and most of the commercially available forms seem to be limited to powders of varying sizes from nanometers to micrometers; how does this substance end up as a dielectric material for a larger capacitor? (While maintaining its uniquely high K, that is) Is it through sintering, or through suspension in a binding polymer?

Also, if it is through sintering, does that cause a limitation in the sizes of the plates, potentially affecting its application in very large capacitors for, say, electric vehicles?

Thanks.

1. What is Barium Titanate?

Barium Titanate is a chemical compound composed of barium and titanium ions. It has the chemical formula BaTiO3 and is commonly used as a dielectric material in electronic devices.

2. What is the difference between sintered and polymer barium titanate?

Sintered barium titanate refers to the process of heating and compressing the compound to form a solid material, while polymer barium titanate refers to the incorporation of barium titanate particles into a polymer matrix. Sintered barium titanate is typically used in ceramic applications, while polymer barium titanate is used in flexible electronic devices.

3. What are the properties of barium titanate?

Barium titanate is a ferroelectric material, meaning it can be polarized by an electric field. It also has a high dielectric constant, which makes it useful for capacitors and other electronic components. It is also optically transparent and has piezoelectric properties, meaning it can convert mechanical energy into electrical energy.

4. What are the applications of barium titanate?

Barium titanate has a wide range of applications, including as a dielectric material in capacitors, sensors, and transducers. It is also used in piezoelectric devices, such as ultrasound transducers and actuators. Polymer barium titanate is commonly used in flexible electronics, such as smart clothing and wearable devices.

5. Are there any health concerns associated with barium titanate?

Barium titanate is considered safe in its solid form, but caution should be taken when handling it in powder or dust form. Inhaling barium titanate particles can irritate the respiratory system and may cause lung damage. As with any chemical, it is important to follow proper safety precautions when working with barium titanate.
