伊藤黒鉛工業 List of Products and Services

"Special Carbon Products" are products that are stronger and much lighter than regular graphite, and they are increasingly being used in industrial fields such as "high-temperature furnace components" and "heat treatment trays." [Features] ■ Higher strength than regular graphite ■ Very light, about one-fifth the weight of iron and one-half the weight of aluminum ■ Low thermal conductivity, with reduced strength degradation at high temperatures compared to metals ■ Extremely low thermal expansion rate, capable of withstanding high temperatures close to 2000℃ *For more details, please download the PDF or feel free to contact us.

Ito Graphite Industry Co., Ltd. has been pursuing new possibilities of graphite for over 70 years as a manufacturer of graphite powder. Graphite has five excellent properties: "lubricity," "electrical conductivity," "thermal conductivity," "heat resistance," and "chemical resistance," and is used in various applications such as pencil leads and sealants. 【Five Excellent Properties of Graphite】 <Lubricity> - Used as a lubricant or release agent, especially in high-temperature and high-load environments. - The layers of flaky graphite are easily peeled off, due to their complete cleavage in the horizontal direction. <Electrical Conductivity> - Less prone to oxidation compared to copper and more affordable than silver and gold, making it widely used. <Thermal Conductivity> - Exhibits excellent thermal conductivity because the mechanism of heat transfer is similar to that of electricity. <Heat Resistance> - Oxidation begins at about 500°C in an oxidizing atmosphere, but remains stable up to 3500°C in a reducing atmosphere. <Chemical Resistance> - Stable against both acids and alkalis. *For more details, please feel free to contact us.

The product "Spherical Graphite" from Ito Graphite Industry Co., Ltd. is made by spheroidizing flake graphite. Typically, flake graphite has a high degree of orientation, but spheroidization reduces this orientation. Additionally, in its powdered form, it has a higher electrical conductivity compared to flake graphite. For those who wish to receive a sample, we offer a free provision of "a total quantity of 1kg, up to 5 types." Please apply for a sample through the inquiry section on our website. 【Features】 ■ Spheroidized flake graphite ■ Generally, flake graphite has a high degree of orientation, but spheroidization reduces this orientation ■ In its powdered form, it has a higher electrical conductivity compared to flake graphite *For more details, please feel free to contact us.

The product "Thermal Decomposition Graphite" from Ito Graphite Industry Co., Ltd. is obtained by heat treating powdered coke at over 2500°C, resulting in graphitization. Specifically, it is produced as a byproduct when generating SiC (silicon carbide). Its appearance is similar to flake graphite, consisting of thin flakes. It has a higher purity compared to natural graphite. Furthermore, the diameter of the impurity silica is finer compared to flake graphite.
