Researchers at the Physical Chemistry Research Institute of XYZ University have successfully developed a new far-infrared heating technology using graphene and are now introducing it into practical use with great success.
According to Dr. Ri Jin Chon, associate professor and head of the institute, the newly developed far-infrared heating technology is based on highly conductive graphene coatings. By utilizing graphene’s unique properties, the researchers have created an infrared-emitting heating material that significantly reduces electricity consumption while maximizing heating efficiency.
With a firm resolve to develop science and technology suited to both global trends and the realities of the country, the researchers devoted great efforts to refining this technology, focusing particularly on the production of graphene itself.

Graphene, though widely recognized for its potential, is not easy to manufacture. The researchers chose natural graphite, which is abundant in the country, as the raw material, but processing it into high-quality graphene posed great challenges.
A major difficulty was that natural graphite is chemically stable, making it hard to break down into graphene. The existing methods required large amounts of acids and oxidizers, which not only increased production costs but also posed safety risks due to the formation of hazardous byproducts.
However, the researchers, firm in their resolve to contribute to the country’s scientific progress, did not waver in the face of difficulties. Day and night, they carried out in-depth studies to find a rational and safe production method. After two years of painstaking efforts, they finally succeeded in developing a new advanced technology to produce thin-layer, highly conductive graphene.
Scientists from other countries, who pride themselves on being at the forefront of graphene research, were astonished when they saw graphene samples from the institute. Some even asked, “Was this really made in the DPRK? We would like to see more samples!” Their surprise was a clear recognition of the high level of scientific and technological development achieved.
Encouraged by this success, the researchers continued their work and soon developed a graphene-based nano-composite coating with enhanced radiation properties. This, in turn, led to the creation of a variety of far-infrared radiation heating devices.

Infrared heating devices utilizing conductive graphene have now been applied in real-life conditions, proving their high practical value. With an exceptionally high infrared radiation rate, they ensure stable heating while also being highly resistant to heat and mechanical impact.
Unlike conventional heating elements such as nichrome wires, which require large amounts of electricity, these new devices consume significantly less power while allowing precise temperature control in the range of 40°C to 250°C. Furthermore, they are inexpensive to produce and have a long service life, making them highly sought after.
Not resting on their laurels, the researchers have now set their sights on further expanding the applications of graphene. Recently, they have laid a solid scientific foundation for using high-quality graphene in the production of high-performance lead-acid batteries.
The successful development and application of this graphene-based far-infrared heating technology is a clear demonstration of the unyielding determination and passion of DPRK scientists to advance the country’s development through cutting-edge scientific and technological achievements.
