APAKAH MAKSUD BERYLLIUM dalam CORSICA?
Beryllium
Beryllium adalah unsur kimia dengan simbol Be dan nombor atom 4. Oleh kerana setiap berilium yang disintesis dalam bintang adalah jangka pendek, ia adalah unsur yang relatif jarang di alam semesta. Ia adalah unsur divalen yang berlaku secara semulajadi hanya dalam kombinasi dengan unsur-unsur lain dalam mineral. Batu permata terkenal yang mengandungi berilium termasuk beryl dan chrysoberyl. Sebagai unsur bebas ia adalah keluli logam kelabu, kuat, ringan dan lemah alkali tanah rapuh. Beryllium meningkatkan banyak sifat fizikal apabila ditambah sebagai elemen mengaloi kepada aluminium, tembaga, besi dan nikel. Alat-alat yang diperbuat daripada aloi tembaga berilium kuat dan keras dan tidak membuat percikan apabila mereka menyerang permukaan keluli. Dalam aplikasi struktur, gabungan ketegaran lentur yang tinggi, kestabilan haba, kekonduksian terma dan ketumpatan rendah menjadikan logam berilium sebagai bahan aeroangkasa yang sesuai untuk komponen pesawat, peluru berpandu, kapal angkasa, dan satelit. Kerana ketumpatan rendah dan jisim atomnya, berilium relatif telus kepada sinar-X dan bentuk lain radiasi pengion; Oleh itu, ia adalah bahan tetingkap yang paling biasa untuk peralatan X-ray dan komponen eksperimen fizik zarah.
Definisi beryllium dalam kamus Corsica
Takrif berilium dalam kamus adalah elemen metalik logam perak putih yang tahan karat yang berlaku terutamanya dalam beril dan digunakan terutamanya dalam tingkap X-ray dan pembuatan aloi. Simbol: Jadilah; atom tidak: 4; atom wt: 9.012; valensi: 2; ketumpatan relatif: 1.848; lebur pt: 1289 ° C; mendidih pt: 2472 ° C Bekas nama: glucinum, glucinium.
