Pengenalan

• Berilium ditemui oleh ahli farmasi Perancis Louis Nicolas Vanquelin pada tahun 1798.

• Beliau menetapkan bahawa logam baru ini adalah satu komponen

• beryl dan zamrud. • Berilium adalah unsur keempat Jadual berkala

yang mempunyai simbol "Be".

• berilium lebih ringan satu pertiga daripada aluminium, namun mempunyai enam kali kekukuhan tertentu keluli.

• keras yang rapuh pada suhu bilik dan mempunyai struktur kristal heksagon hampir penuh.

• Takat lebur yang agak tinggi.

Jenis – Jenis Berylium

• Aquamarine - light bluish green form of beryl. it is much harder than apatite. Aquamarine is most often found in pegmatite's of granite (Aquamarine).

• Bixbite- is the red form of beryl. It is an extremely rare mineral,No forms of bixbite have ever been found outside of the United States. Bixbite forms in volcanic rocks that are rich in silica. It forms due to low pressures and high temperatures. The red color comes from inclusions of manganese in the beryl itself (Bixbite).

• Emerald - It is a green mineral. Emerald gets its green color from inclusions that come from both chromium and iron. Columbia is well known for its emerald deposits. Emerald is most often found in mica schist. These occur in hydrothermal areas.

• Goshenite - simply a form of beryl that lacks color. However, this does not mean that it does not have any impurities or inclusions. There are many impurities that can lead goshenite to have no color. This type of beryl can be found in many areas of the world. It is most commonly located where other various types of beryl are located (Goshenite).

• Heliodor - yellow from of beryl. The amount of iron inside of the beryl allows heliodor to have many different shades of yellow. Heliodor is most commonly found granite pegmatite's. Sometimes, clear beryl can be formed from heliodor. This can be done by heating the heliodor to great temperatures to decrease the concentration of the impure iron.

• Morganite- pink form of beryl. It is known to often occur in pegmatite granites. Both manganese and iron give morganite its pink to yellow color. Morganite is found in four different U.S states and in two other countries. Morganite got its name from an American.

LANGKAH MENCEGAH PENYAKIT YANG DISEBABKAN BERILIUM

• Menggunakan pelet bukannya serbuk boleh membantu mengurangkan pendedahan.

• Proses penutup memisahkan pekerja daripada bahan-bahan yang berbahaya.

• Sistem ekzos tempatan yang mencukupi mengelakkan bahan-bahan toksik daripada KELUAR ke dalam bilik kerja.

• Pekerja perlu menggunakan proses basah.• PPE
