Ceramic and glass industry, lithium battery industry, etc.
1. Hectorite powder is widely used in ceramic and glass industries. It can be used as ceramic raw material for manufacturing electrical ceramics and ceramic pigments. In the glass industry, lithium feldspar powder can be used as a glass solvent and mineralizer, helping to improve the quality and performance of glass.
2. Lithium feldspar powder is one of the important raw materials in lithium battery industry. Can be used to prepare cathode materials and separators for lithium-ion batteries. Lithium-ion batteries are important energy storage devices widely used in mobile electronic devices and electric vehicles.
I think first of all, PTC translated from Chinese meanse positive temperature coefficient. Generally speaking, PTC is a semiconductor material, and the positive temperature coefficient of this semiconductor material is very large. In applications, the PTC often appears as a thermistor, and the lithium battery protection board uses the high resistance of the device material to become a circuit breaker in disguise, cutting off the current to achieve protection. With this explanation, everyone will do it. I think PTC is a very important component in lithium battery protection board and the main protection function is also achieved through it.
It is short for Positive Temperature Coefficient, which means positive temperature coefficient, and generally refers to semiconductor materials or components with a high positive temperature coefficient. Usually the PTC we are referring to refers to thpositive temperature coefficient hermistor, or PTC thermistor for short. PTC thermistor is a typical temperature sensitive semiconductor resistor when it exceeds a certain temperature (Curie temperature), its resistance value increases gradually as the temperature increases. PTC ceramic is mainly composed of barium titanate (or strontium, lead), with a small quantity of donor elements (Y, Nb, Bi, Sb), acceptors (Mn, Fe), and glass (silicon oxide, alumina) and other additives. , semiconductor ceramics formed by sintering. PTC (positive temperature coefficient) is a heat-sensitive material with a positive temperature coefficient, which has the characteristic that the resistivity increases with temperature. In 1955, Heimann and others at the Philips company in the Netherlands discovered that after adding traces of rare earth elements to BaTiO3 ceramic, its temperature resistivity increasedambient temperature decreased considerably and its resistivity could increase by three orders of magnitude in a very narrow temperature range. Above, we first learned about the characteristics of PTC materials. For more than 40 years, PTC materials have been
