Dr. NargesAjami on Instagram‎: "✨ پیریت (pyrite) با فرمول شیمیاییFeS2 طلای ابلهان یا گنج زمین‌شناسی؟ ✨ پیریت، این کانی درخشان با رنگ طلایی فریبنده، قرن‌هاست انسان‌ها را وسوسه می‌کند! اما برخلاف ظاهر جذابش، ارزش واقعی آن نه در طلا بودن، بلکه در اسرار علمی‌ای است که در ساختار بلوری‌اش نهفته. 🔬 دانستنی‌های علمی کوتاه: ▪️ فرمول شیمیایی: FeS₂ (سولفید آهن) ▪️ سختی موس: ۶-۶.۵ (به اندازه‌ی یک تیغ فولادی!) ▪️ سیستم بلوری: مکعبی؛ گاهی مکعب‌های کامل با خطوط منظم روی وجوه ▪️ کاربرد تاریخی: در ساخت 🔋 باتری
