High purity Black Phosphorus - crystal pieces - 500 mg We are one of the most biggest supplier for layered high purity black Phosphorus worldwide and can provide samples up to several hundred grams per week. Layered bulk Black Phosphorus 0.5g - 99.998% purity sealed in ampoule under Argon NOW IN STOCK! High pure black Phosphorus crystals produced by gas phase transport - The highly shiny and very stable crystals have a bluish black metallic luster. You get 1 - 2 crystal clusters from which single crystals can be isolated. By scotch tape method very thin '2D-Layers' can be obtained. These samples are perfecty suited for semiconductor experiments. For analysis data (XRD, Raman, TEM, TGA) please send a request. Selected science papers where our material has been used can be obtained on request. You get ONE ampoule! There are several forms of phosphorus. White phosphorus is manufactured industrially, glows in the dark, is spontaneously flammable when exposed to the air above 30°C and is a deadly poison. Red phosphorus, made by gently heating white phosphorus in the absence of air to about 250°C, does not glow, is stable and is not poisonous. This is the material, mixed with powdered glass, stuck on the side of boxes of safety matches on which the matches must be struck to light them. Phosphorus itself is essential to all forms of life since it is part of DNA, although there are many phosphorus compounds that are essential in the living cell. We take in about 1 gram of phosphate a day, and we store about 750 grams in our bodies, since our bones are mainly calcium phosphate. In the environment and in living things, phosphorus is present as phosphate, which consists of one phosphorus atom at the centre of four oxygen atoms. Phosphates are used in fertilisers and detergents and in metal coatings to prevent corrosion. However, excess phosphates in rivers and lakes cause an over-growth of slimy green algae, which robs the water of its life-supporting oxygen. scope of delivery You get one ampoule of High purity Black Phosphorus - crystal pieces - 1 gram shipping fees We calculate following shipping fees: Table of shipping fees: Standard International Airmail (5 - 10 days lead time)USA, Canada$26.90Asia, South America, Africa$31.50Australia, New Zealand, Oceania$37.00 Courier Express Services:Items up to 1kg (2.2lbs) by Courier Express (Very fast! 1 - 3 days lead time )USA, Canada$125.00Australia, New Zealand, Asia and other countries outside EU$152.30 Items over 1kg up to 2kg (4.4lbs) by Courier Express (Very fast! 1 - 3 days lead time ) USA, Canada$133.40Australia, New Zealand, Asia and other countries outside EU$169.70 I am happy to combine shipping to save you money!
