Scandium Fluoride Industrial Grade 99.99%

Scandium fluoride is white powder or 3-12mm porous particle of cubic crystal system, which is rare earth metal fluoride. It is stable at room temperature and pressure. Its solubility in water is tiny, but soluble in alkali carbonate and sal volatile. It decomposes completely when melting with alkali. Scandium chloride, scandium nitratescandium metal, scandium hydroxide or scandium oxide is the raw material. Its synthetic method is same as lanthanum fluoride. ScF3 show extraordinary negative thermal expansion property that mean it shrink when heating.

Selenium Powder Industrial Grade 99.9%

Selenium powder is black amorphous particle, which is a kind of nonmetal. After heating, it cool to glassy form. Its monoclinic crystal is red, however hexagonal crystal is grey. It is insoluble in water, hydrochloric acid and dilute sulphuric acid, but soluble in nitric acid, carbon disulfide, benzene and quinoline. High purity selenium and nano selenium powder are both available. Selenium granules are available too.

Selenium Powder

Purity: 99.99%, 99.999%, 99.9999%

CAS No.:7782-49-2 EINECS No.:231-957-4 Molecular Formula:Se Molecular Weight:78.96
Melting Point:220.2℃ Boiling Point:685℃ Density:4.82  

Applications

Pure selenium is mainly for selenium dioxide production, which is catalyst for electrolytic manganese smelting.

High purity selenium is raw material for production of zinc selenide compounds, powder of xerography and other metal selenium compounds.  It is for epitaxial diffusion process of semiconductor productions.  It apply to selenium rectifier, phototube, photocell, radio communications copy and photograph.

Selenium nano powder is an kind of analytical reagent too. It can as dehydrogenating agent of aromatic compounds.
