কোরিয়ানএ 루테늄 এর মানে কি?
রূটীনিয়মপদার্থ
Ruthenium একটি রাসায়নিক উপাদান প্রতীক আরু এবং পারমাণবিক সংখ্যা 44 সঙ্গে। এটি প্লাটিনাম গ্রুপের অন্তর্গত একটি বিরল স্থানান্তর ধাতু। এটি প্ল্যাটিনাম অরে একসঙ্গে তৈরি করা হয় এবং প্ল্যাটিনাম অ্যালোয়েজগুলির একটি অনুঘটক হিসেবে ব্যবহৃত হয়। এটি লাতিনিয়াতে উৎপত্তি, যার অর্থ রাশিয়ান, ল্যাটিন ভাষায়।
কোরিয়ানএর অভিধানে 루테늄 এর সংজ্ঞা
রূটীনিয়মপদার্থ পর্যায়ক্রমিক সারণির 8 ম থেকে 5 ম পর্যায়কালের পরিবর্তিত ধাতু হল মৌলিক উপাদান রূ, পারমাণবিক ওজন 101.07 গ্রাম / মোল, গলনাঙ্ক 2334 캜, উষ্ণায়নের পয়েন্ট 4150 캜 এবং ঘনত্ব 12.45 গ / সেমি 3। প্ল্যাটিনাম মত দেখতে সিলভার ধূসর বিরল মৃত্তিকা উপাদান কিন্তু প্ল্যাটিনাম এবং ফাটল ভাল তুলনায় কঠিন। এটি প্ল্যাটিনাম এবং প্যালিডিউএল এর কঠোরতা বৃদ্ধি একটি alloying এজেন্ট হিসাবে ব্যবহার করা হয়।
