Introduction to isostatic pressed graphite materials

Isostatic pressed graphite is made of high purity graphite, isostatic pressed graphite is a new product developed in the world in the past 50 years, and is closely related to today's high-tech.
It is not only useful in civilian use, but also occupies an important position in the forefront of national defense, and is a new type of material. It is an irreplaceable material for the manufacture of single crystal furnaces, metal continuous casting graphite crystallizers, graphite electrodes for EDM processing, and is an excellent material for the manufacture of rocket nozzles, graphite reactor deceleration materials and reflective materials.

Properties of isostatic pressed graphite materials

Isostatic pressed graphite has a high purity, usually reaching more than 99% carbon content. It also has a high density, which can be achieved through the isostatic pressing process, and provides better physical and chemical properties.

Excellent thermal conductivity

Isostatically pressed graphite has extremely high thermal conductivity, making it an ideal material for thermal management applications. It is widely used in heat exchangers, radiators, cooling devices and other fields.

Excellent mechanical properties

Isostatically pressed graphite has high strength and rigidity and can withstand large forces and strains. This makes it widely used in aerospace, mechanical engineering and other fields that require high-strength structural materials.

Corrosion resistance

Isostatically pressed graphite has good corrosion resistance to chemicals and can operate stably in harsh environmental conditions for a long time. Therefore, it is widely used in the chemical industry and corrosive media.

Hengsheng graphite material

The company standards the international first-class production process and product indicators, after years of high intensity research and development investment, Hengheng isostatic pressing graphite materials have met the needs of photovoltaic and semiconductor silicon single crystal growth, silicon carbide substrate and epitaxial growth, granular silicon, graphite vessels, EDM, advanced ceramics and other fields, breaking the monopoly of foreign manufacturers in the field of high-end isostatic pressing graphite. The existing production capacity is 15,000 tons, and the production capacity under construction is 30,000 tons. Its isostatic pressing one-time molding, one-time roasting and internal series graphitization process is in the international leading level.

HS677material introduction

Specially for the production of photovoltaic products, in the process of roasting, impregnation, graphitization, the temperature and the loading method of the specific production process to make the resistivity meet the needs of the single crystal thermal field resistance, the same density will be increased, the electrical conductivity will be stronger, the thermal conversion coefficient will be more stable, the heat uniformity will be better, and the thermal shock resistance will be better.

HS677material advantage

The material with stable resistivity and high density has better thermal conversion coefficient stability and heating uniformity. On the contrary, the degree of graphitization of materials with unstable resistivity is relatively poor, the temperature is not uniform, and the local temperature is too high, which will lead to the instability of the thermal conversion coefficient. At present, the photovoltaic industry's ideas for thermal field design have gradually turned to low-resistance materials, and the performance of heater life and stability also confirms the advantages of this grade of materials.
