What are the differences between No. 0, No. 1, and No. 2 refined antimony?
Did you know, Antimony actually exists in many aspects of our lives, it can be said to be everywhere. So next, let me tell you No. 0, No. 1, No. 2 What are the differences and specific uses of these antimonys?
Antimony, also known as antimony ingot, is an important raw material for various industries. It is mainly used as an alloy hardener in metallurgy, batteries, and military industries. It is also one of the raw materials for producing antimony oxide. Antimony ingots can also be used in mobile printing industries, lead materials, cable sheaths, solders, sliding bearings, etc. The chemical element symbol is Sb, which is a brittle, luminescent, silvery-white solid. Antimony is a colored heavy metal. There are two allotropes, the yellow variety is stable at -90 degrees, and the metallic variety is the stable form of antimony. Melting point 630, density 6.62 g/cm3, poor thermal conductivity.
But according to the purity of antimony ingots, they can be divided into No. 0 antimony, No. 1 antimony, and No. 2 antimony. Let's see what the differences are!
No. 0 antimony
Antimony content 99.90%, is an important basic raw material for the production of antimony oxide, and is also an alloy hardener for the metallurgical and battery industries in China, and can be used in the movable type printing industry, lead materials, cable sheaths, solders, and sliding bearings, etc. Unlike No. 1 antimony, although its appearance is a blocky truncated hexagonal metal ingot, No. 0 Antimony is a lustrous silvery-white solid, not only with high purity requirements, but also can be used in the design and manufacture of V-cluster compounds as semiconductors, high-purity alloys, and dopants for cold components and germanium single crystals.
No. 1 antimony
The antimony content is 99.85%, which is an important raw material for the production of antimony oxide, and is also an alloy hardener for the metallurgical and battery industries. It can be used in the movable type printing industry, lead, cable sheaths, solders, sliding bearings, and can also be widely used in inks, rubber, paints, paints, ceramics, chemical fibers, medicine, food, etc. The appearance is a huge truncated hexagonal metal ingot, unlike No. 0 antimony, No. 1 is a silvery-white solid and dull.
No. 2 antimony
Content 99.50%, is an important basic raw material for the production of antimony oxide, and is also an alloy hardener for the metallurgical and battery industries in China, and can be used in the movable type printing industry, lead materials, cable sheaths, solders, and sliding bearings, etc. The appearance is a silvery-white blocky crystalline material, with a beautiful pattern formed on the surface.
Note: Refined antimony must be protected from moisture, rain, and packaging damage during transportation, otherwise it will affect the purity of the refined antimony.
Next, let me introduce to you Antimony how it is extracted.
The extraction of antimony is a method of extracting refined antimony from lead-antimony concentrate using the sulfide alkali method. The leaching solution is circulated and sprayed to introduce air to enhance the oxidation of antimony. The waste liquid needs to be continuously evaporated to obtain mixed sodium sulfate crystals. The reduction and calcination, the calcination slag is leached with evaporated condensate, and the sodium sulfide solution can be recycled and effectively utilized. Using this method to extract antimony does not require electrolysis, the lead-antimony separation is fast, and the reduced antimony can be refined again to reach the No. 1 antimony standard.
The above is an introduction to No. 0, No. 1, No. 2 What are the differences between antimonys? If you want to learn more, please contact us! We look forward to your participation and consultation at any time.
