ما هو عنصر البورون

استخدامات البورون

رباعي بورات الصوديوم decahydrate أو البوراكس هو أهم مركب compound من البورون ، والذي يستخدم لعزل الألياف الزجاجية ومبيض بيربورات الصوديوم sodium.
حمض البوريك boric acid هو أحد المركبات الهامة في منتجات المنسوجات. تستخدم مركبات البورون أيضًا في التخليق العضوي ، ونوع معين من صناعة الزجاج وكمادة حافظة للأخشاب.
تم استخدام البوراكس borax سابقًا في صنع البربورات ، وهو عامل التبييض المستخدم على نطاق واسع في بعض المنظفات.
توجد مركبات البورون أيضًا في المنازل على شكل مواد حافظة غذائية ، خاصة للأسماك والسمن النباتي.

خصائص البورون

إنه موصل ضعيف للكهرباء ويمكن العثور عليه أيضًا في السيراميك ceramic والبنادق المضيئة والنظارات المصنوعة من الألياف.
يحتوي البورون على عدة أشكال والبورون غير المتبلور وهو مسحوق غامق وغير متفاعل مع الأكسجين والماء والقلويات والأحماض هي الأكثر شيوعًا. يشكل البوريدات عندما يتفاعل مع المعادن.

حقائق معينة عن البورون

يوجد البورون في أكثر من مائة معدن على الأرض. لكن من الصعب للغاية إنتاجه ، حتى في ظروف المختبر.
البوروميسين مضاد حيوي طبيعي يحتوي على البورون. وهو مشتق من Streptomyces.
