What are the differences between high-purity graphite rod and high-strength graphite rod? These problems have always been something graphite people should understand.

High purity graphite refers to the carbon content of Graphite & gt; 99.99%, widely used in advanced refractory materials and coatings in the metallurgical industry, stabilizers for initiating explosive materials in the military industry, pencil leads in the light industry, carbon brushes in the electrical industry, electrodes in the battery industry, and catalyst additives in the fertilizer industry.

Characteristics of high purity graphite

High purity graphite has the advantages of low resistance coefficient, high temperature resistance, corrosion resistance, oxidation resistance, good thermal shock resistance, low conductivity, thermal expansion coefficient, self lubrication, and easy precision machining.

Both high-purity graphite and high-carbon graphite are graphite products with high carbon content. The difference between high-purity graphite and high-carbon graphite is that the carbon content of high-purity graphite is higher than that of high-carbon graphite,

First of all, let's talk about high-purity graphite rod, which is a graphite block made of high-purity graphite powder by grinding and sintering, and then processed into a graphite rod after cutting. It has the characteristics of high purity, high density and high strength. Generally, the powder is not 325 mesh or finer. At present, some manufacturers of isostatic pressing graphite materials have reached 1000 mesh fineness. His processing is specifically processed into round bars by a lathe, so the cost is relatively high, but the cost performance ratio is good, and the oxidation resistance is good. It is generally used in some fine industries.

High strength graphite mainly refers to high strength, high density and high purity graphite products (referred to as "three high graphite"). Three high graphite can be divided into three types: coarse-grained structure, fine-grained structure and ultra-fine-grained structure in terms of material structure. From the perspective of molding method, they are mainly divided into three types: special graphite formed by molding, special graphite formed by extrusion and special graphite formed by isostatic pressing. In addition, vibration molding can also be used to produce special graphite. High quality special graphite isotropic graphite is a special graphite produced by isostatic pressing process.
