Isostatic pressing graphite is made of high purity graphite. Isostatic pressing graphite refers to the use of isostatic pressing method of production of graphite materials, also known as "isotropic" graphite. Isostatic pressing is to press the material after being sealed in the high-pressure container, the use of liquid media can not be compressed nature and uniform transmission of the nature of the material from all directions to the material uniform pressure. According to the principle of fluid mechanics, the pressure of the same size and uniform transmission to all directions, so the high-pressure container powder in all directions by the pressure is uniform and uniform size.

The method of making the powder compact into the green body by this method is called isostatic pressing. In accordance with the static pressure forming temperature division, can also be divided into cold isostatic pressing, temperature isostatic pressing and hot isostatic pressing.

Isostatic pressing graphite has the following advantages:

Suitable for large-scale molding, suppression of special-shaped products. Due to the use of liquid pressure, indicating uniform compression; pressure up to

160-200Mpa even higher, high compressive strength, so suitable for pressing large-scale products. Can change the shape of the mold directly pressed into a different shape blank.

Material structure is dense and uniform, high hardness, high strength. Liquid pressure, the product uniform force; optional pressure time and control the pressure relief pressure, the release of pressure after the product elastic effect is small, is to suppress the ultra-fine structure of one of the prerequisites; pressure, high strength, And the strength is high.

Isotropic (characteristic independent of size, shape, sampling direction). As the liquid pressure, the same pressure, the products are isotropic. Good thermal shock resistance, high temperature. The material is not easy to crack under the conditions of rapid cooling and hot working conditions, and the oxidation resistance is strong.

Isostatic graphite with high strength, high density, high purity, high chemical stability, dense structure, high temperature, radiation resistance, high conductivity, good wear resistance, self-lubricating, easy processing and other characteristics, widely used in Metallurgy, chemical industry, aerospace, electronics, machinery, nuclear energy and other industrial fields. In particular, large-scale high-quality special graphite, as an alternative material, in high-tech, new technology has a broad application space, with a wide range of applications.

Isostatic graphite is the international nearly 50 years to develop new products, and today's high-tech are closely linked. Not only in civil use as much, in the national defense tip occupies an important position, are new materials. It is the manufacture of single crystal furnace, metal continuous casting graphite mold, EDM graphite electrode and other irreplaceable materials, but also the manufacture of rocket nozzles, graphite reactor deceleration materials and reflective material of the excellent material.
