High pure Zno powder has three lattice structures: hexagonal wurtzite structure, cubic sphalerite structure and cubic rock salt structure. Hexagonal wurtzite is the most thermodynamically stable crystal structure under natural conditions, and it can only exist stably by growing on a hexagonal substrate. The existence conditions of cubic zinc sphalerite and cubic rock salt structure are relatively harsh and can only be obtained under high pressure conditions.

High pure Zno powder material has the following advantages: photoelectric thermoelectric piezoelectric ferroelectric ferromagnetic
1. High pure Zno powder is a kind of piezoelectric and thermoelectric semiconductor material with good performance, which can be used in surface acoustic wave devices, body surface wave devices, pressure sensitive devices, catalysts, gas sensors, batteries, electromechanical regulators and other fields;
2. Ferroelectricity: In some dielectric crystals, the structure of the unit cell makes the center of gravity of positive and negative charges do not coincide and an electric dipole moment appears, resulting in an electric polarization intensity that is not equal to zero. This is the nature of crystals that emit spontaneous aurora. High pure Zno powder 's polarity along the c-axis direction and the existence of polar planes and surface polarization give it ferroelectric properties and is an ideal material for studying polar induced ferroelectric properties.
3. Ferromagnetism: It means that the magnetic moments of adjacent atoms or ions in a substance are arranged in the same direction in some areas due to their interaction. When the applied magnetic field strength increases, these areas are aligned with the total magnetic moment. The degree will increase to a certain and limited phenomenon. Zno powder -added materials are ferromagnetic.
