In ancient times, Sulphur (CAS 9035-99-8) had many aliases, such as Shiliu Huang, Shiliu Huang, Kunlun Huang, etc. These names are as varied as its stature, containing an ancient and mysterious aura. In the Eastern Han Dynasty's Shennong Ben Cao Jing (Classic of the Materia Medica of the Divine Husbandman), sulphur was described as 'sour, warm, poisonous; attributed to the kidney and large intestine meridians,' and was used to treat scabies, eczema, itchy skin and other conditions, as well as being used internally to tonify the fire and help the yang. Li Shizhen in the 'Compendium of Materia Medica' even called it 'stone sulfur yellow', 'general', 'Yang Hou', praising its nature of circulation, colour endowed with the yellow, with a strong yang, tonic sinew and bone strain, and so on. Effectiveness. These records, like a vivid picture, depicting the wide range of applications of sulphur in ancient medicine and life.
In modern times, sulfur powder (7704-34-9 or CAS 7704-34-9) and insoluble sulfur still play an important role in our lives, but their uses have far exceeded the ancient scope. Sulphur powder is widely used in many fields such as medicine, agriculture, beauty and so on because of its multiple effects such as disinfecting and sterilising, controlling pests and diseases, skin care and beauty. In medicine, sulphur powder is often used to treat skin diseases, and its bactericidal effect can effectively kill bacteria, fungi and viruses, but you should always ask your doctor when using it.
So, how are these amazing substances made? Sulphur powder is usually produced by crushing sulphur lumps or natural sulphur ore into fine powder form, and then heating it in airtight, and then continuing to raise the temperature after the sulphur melts, so as to sublimate it into fine powdered sulphur. Insoluble sulphur, on the other hand, is a transparent, amorphous chain-like structure of elastic sulphur obtained by heating ordinary sulphur to boiling and then pouring it into cold water and cooling it rapidly, or it is produced by other methods such as gasification method, contact method, radiation method, low temperature liquid phase method and so on. These production methods, like the magic of modern technology, give new life and vitality to the ancient sulphur.
Sulphur is formed by the essence of pure sun and firestone', this ancient poem not only depicts the magical origin of sulphur, but also foretells its wide application and unlimited possibilities in the modern society. From ancient medical artefacts to modern industrial auxiliaries, sulphur powder and insoluble sulphur have travelled through time and space, witnessing the progress and development of human civilisation.
