Product Description

PCB heat cooling alumina purple insulating ceramic parts

Reputation depends on quality, quality comes from Hard!


Alumina Ceramics:

A prerequisite for the growth of anodized film is that the electrolyte should have a dissolution effect on the oxide film. However, it does not mean that anodization can form an oxide film or the same oxide film is formed in all electrolytes in which dissolution exists. Anodizing According to the current form: DC anodizing, alternating current anodizing, pulse current anodizing. According to the electrolyte: sulfuric acid, oxalic acid, chromic acid, mixed acid and natural colored anodizing with sulfoorganic acid as the main solution. The film layer is divided into: anodizing of ordinary film, hard film (thick film), porcelain film, bright modification layer, and barrier layer for semiconductor action. The common anodizing methods and process conditions of aluminum and aluminum alloy are shown in Table-5. Among them, the direct current sulfuric acid anodic oxidation method is most common. The anodized film is composed of two layers, and the porous thick outer layer is grown on a dense inner layer having dielectric properties, the latter being called a barrier layer ( Also known as the active layer). Observed by electron microscopy, the longitudinal and lateral planes of the film layer almost all show tubular holes perpendicular to the metal surface, and they penetrate the outer layer of the film until the barrier layer between the oxide film and the metal interface The barrier layer is composed of anhydrous aluminum oxide, which is thin and dense, has high hardness and prevents the passage of electric current. The thickness of the barrier layer is about 0.03-0.05 μm, which is 0.5%-2.0% after the total film. The pores are surrounded by dense alumina to form a honeycomb hexagonal body called a unit cell. The entire membrane layer is composed of countless such unit cells. When the electrolyte is sulfuric acid, the sulfate content in the membrane layer is normal. The lower layer is 13%-17%. The porous outer layer of the oxide film is mainly composed of amorphous alumina and a small amount of hydrated alumina, and further contains a cation of the electrolyte. Most of the excellent properties of the oxide film are They are all closely related to the anodizing conditions, depending on the thickness and porosity of the porous outer layer.
