No need for hot water, firewood, coal, or electricity to keep warm. This is made possible by a heat-generating material developed by experts from Hanoi University of Science and Technology.

The heat-generating pouch developed by Hanoi University of Science and Technology |
This heat-generating material, encased in small fabric pouches, is particularly useful for homes, hospitals, travel, sports, and defense, as it does not rely on other energy sources for immediate use…
According to project leader Nguyen Dung from the Organic Chemistry Department (Faculty of Chemical Technology), the aforementioned heat-generating material is essentially a mixture of metal powder with particle sizes smaller than 0.1mm, which is inexpensive and readily available in Vietnam.
When warmth is needed, for instance, to heat the feet in cold weather, one simply tears open the protective packaging, takes out the fabric pouch containing the metal powder, and places it inside their shoes. If heat is required on a specific area of the arm, the pouch can easily be affixed with tape to that region.
Upon exposure to air outside the packaging, the mixture of metal powder in the fabric pouch reacts readily with oxygen, releasing enough heat to warm the targeted area of the body. This material generates heat at temperatures of 42-45 degrees Celsius for a duration of 4-6 hours and is intended for single use.
The chemical reaction can be summarized as follows: Metal Powder Mixture X + O2 → Q (heat energy)
The research team is currently refining the technology for synthesizing this heat-generating material, aiming for trial production and registering a utility solution to turn this material into a commercial product for everyday use.
Mr. Dung mentioned that this is the first time such a heat-generating material has been developed in Vietnam. Due to its dry synthesis form, it is easy to store, convenient, and non-toxic. Additionally, the Japanese company Kurashi Moa produces a similar product called Kairo mini, which is used for warming or heating.
