It has high dielectric constant, low dielectric loss, large resistivity, high withstand voltage, and excellent insulation properties. It is widely used in multilayer ceramic capacitors. (MLCC), thermistor (PTCR), electro-optical device, and dynamic random access memory (FRAM), etc., are the basic raw materials of electronic functional ceramic devices, so they are called the backbone of the electronic ceramic industry by scholars and manufacturers. 1. Barium titanate for multilayer ceramic capacitors (MLCC)Multilayer ceramic capacitors, also known as monolithic capacitors, are the most widely used chip electronic components in the world today. They have large capacitance, small dimensions, and good sealing characteristics. MLCC as a basic electronic component has been widely used in mobile communication, home appliances, automotive electronics, aviation and military industries. 2. Barium titanate for positive temperature coefficient thermistor (PTCR)The thermistor device with a positive temperature coefficient is widely used in almost all engineering fields. The PTC thermistor is usually made of barium titanate ceramic material, which has ferroelectric semiconductor barium titanate. When the temperature reaches the Curie point Tc, it changes from a tetragonal phase to a cubic phase. Orders of magnitude (103-107 times), PTCR is based on this characteristic. One of the important applications of PTCR made of semiconducting barium titanate ceramics is the detection and controller of temperature or temperature-related parameters. 3.Barium titanate is used in other special ceramicsPiezoelectric properties refer to the properties of the polarization state of a crystal as a function of applied stress, including positive and negative piezoelectric effects. Based on the good piezoelectric properties of barium titanate, it is mainly used in sound sensors, ultrasonic motors, medical imaging, electronic igniters, buzzers, etc. Packaging & Shipping Package: double antistatic bags, 1kg/bag, 25kg in a drum, or pack as customer requires.
