Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 As shown, the present invention discloses a standardized pretreatment method for testing the components of zinc oxide-based ceramics, including six processes of rough sample cleaning, grinding, secondary cleaning, drying, crushing and alkali dissolution, and the specific method of each process include:

[0023] (1) Take a crude sample of Ga-doped zinc oxide ceramics, and use a decontamination solvent to ultrasonically clean the crude sample. The specific components of the decontamination solvent are ethanol: acetone: decontamination oil=6:2:1.5, above The components are volume ratios; the ratio of crude sample to decontamination solvent is 50g crude sample: 350ml decontamination solvent, and the ultrasonic cleaning time is 2 minutes;

[0024] (2) After the cleaned rough sample is dried, use SiC sandpaper to process the...

Abstract

The invention discloses a standard pretreatment method for testing components of zinc-oxide-based ceramic. The standard pretreatment method comprises six procedures of coarse-sample cleaning, grinding, secondary cleaning, drying, crushing and alkali dissolution. In each specific procedure, the components of the ceramic, the composition, the use amount and the time of a decontaminating solvent, thesize and the mass of the coarse sample, polishing and grinding mediums, the crushing granularity and the specific component proportion and concentration of alkali solution are definitely limited, sothat the standardization and high efficiency of pretreatment are realized and the testing accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of material analysis and testing, and in particular relates to a pretreatment method for component testing of zinc oxide-based ceramics. Background technique [0002] Zinc oxide ceramics are a type of semiconductor ceramic material made of zinc oxide as the main crystal phase and adding appropriate dopants. It has the characteristics of excellent nonlinear coefficient, wide varistor voltage range (a few tenths of volts to tens of kilovolts), small voltage temperature coefficient, fast time response, and small leakage current. The main raw material is zinc oxide, and the dopants include bismuth oxide, cobalt oxide, strontium oxide, titanium oxide, etc. Manufactured by general electronic ceramic technology. It can be used to manufacture voltage stabilizing components and overvoltage protection components in high-voltage circuits (such as low-voltage varistors in integrated circuits), and can also be used as ...
