Initial magnetic-inductive capacity 60 (+12) (-12) nickel-zinc ferrite material and preparation method

Abstract

The invention discloses an oxygen body material of nickel, zinc and ferrum with initial permeability being 60<-12><+12> and a preparation method thereof. The main phase of the material is spinel structure, and the material essentially consists of Fe2O3, ZnO, MnO, NiO and CoO, and the contents of composition calculated by oxide are: 46mol percent to 49mol percent of Fe2O3, 8mol percent to 14mol percent of ZnO, 0.1mol percent to 1.0mol percent of MnO, 35.7mol percent to 42mol percent of NiO and 0.3mol percent to 1.5mol percent of CoO; the oxygen body material of nickel, zinc and ferrum with initial permeability being 60<-12><+12> has broadband, low electromagnetic consumption and good stability in larger working current and can be used for producing various power couplers of high-frequency electroless lamps with the working frequency in range of 2.5MHz to 3MHz; the material has extremely low electromagnetic consumption in high frequency ranging from 2.5MHz to 3MHz; when the frequency isin the range of 2.5MHz to 3MHz, the quality factor Q is more than 240, and the material has extremely high Curie temperature which is more than 300DEG C; due to such high Curie temperature, the material can ensure that the electroless lamp can work smoothly even if the temperature is higher, thus being beneficial to the miniaturization of the electroless lamp.

Description

technical field

[0001] The invention relates to a nickel-zinc ferrite material that can be used to make various high-frequency electrodeless lamp power couplers with an operating frequency within 80MHz, especially a kind of nickel-zinc ferrite material with an initial magnetic permeability of 60 -12 +12 Nickel zinc ferrite material and preparation method thereof. Background technique

[0002] High Frequency Electronic Discharge Lamp (High Frequency Electronic Discharge Lamp) is a high-tech new light source that integrates the latest electronic power-saving technology and electric light source technology. It does not use a filament, but uses a magnetic field to stimulate gas discharge and light emission. It is highly efficient, energy-saving, and environmentally friendly. , long life and many other advantages. The high-frequency electrodeless lamp is composed of three parts: the excitation power supply, the power coupler and the bulb. The excitation source generates an elec...
