Zinc oxide has been around for many years, though people didn’t recognize it as such when they first encountered it. Historical records show that humans used zinc oxide to make medicines and paints long ago. Let’s explore the development of zinc oxide.
By 200 BC, zinc oxide had appeared in Rome, where locals reacted copper with oxygen-containing zinc ore to produce brass. By the 12th century AD, Indians had discovered zinc and zinc ore, using primitive methods to process it. After entering China in the 17th century, zinc gained a corresponding place in the Chinese market. During the same period, Britain established Europe’s first zinc smelter.
In 1834, zinc made its debut as a coating material. By 1850, it had gained popularity across Europe. Due to its high purity, many artists favored it as a base color for paintings.
By the late 20th century, zinc oxide entered the rubber industry. In the 1970s, it became an additive for composite paper, though this practice ceased by the 21st century.
In the 21st century, zinc oxide was discovered through specialized processing to possess excellent fluorescent properties. Its nanoparticles exhibit stable luminescence, capable of sustained glow for 24 hours at a cost equivalent to just 1% of fluorescent proteins, leading to its widespread adoption.
The evolution of zinc oxide can be described as a journey of unlocking its functionalities. As its capabilities were progressively uncovered, it has emerged as a versatile inorganic compound.
