In the Middle Ages, the alchemist Jaber is believed to have isolated metallic antimony. In the 17th century, the German chemist Andreas Libavius \u200b\u200bfurther studied methods for producing antimony. In 1783, the Swedish scientist Anton von Swab first discovered pure antimony in nature, laying the foundation for subsequent scientific research.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h2 class=\"wp-block-heading has-ast-global-color-0-color has-text-color has-link-color wp-elements-ba2968d2b5cf30559aecee264124fdd4\" id=\"&#x92BB;&#x7684;&#x4ECB;&#x7D39;\">Introduction to Antimony<\/h2>\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/honwaygroup.com\/wp-content\/uploads\/2025\/09\/&#x9511;-Antimony.webp\"><img decoding=\"async\" src=\"https:\/\/honwaygroup.com\/wp-content\/uploads\/2025\/09\/&#x9511;-Antimony.webp\" alt=\"\" class=\"wp-image-127749\"\/><\/a><\/figure>\n\n<p class=\"has-medium-font-size\">Antimony (symbol Sb, derived from the Latin word <em>Stibium<\/em>), atomic number 51, atomic weight 121.760.
