The Applications of Amorphous Boron Powder

Amorphous Boron Pulver An element boron, which is either a brown or black powder. It can be oxidized in air to prevent internal boron being oxidized by the formation of a trioxide film. Boron is insoluble in water,boron powder is soluble in boiling nitric acid and sulfuric acid,and most molten metals such as copper,iron,manganese,aluminum and calcium.The content of boron in the earth's crust is 0.001%.Boron is black or silver Gray solid.Crystal boron is black,the hardness is second only to diam

Difference between CuO and Cu2O

Cu2O is obtained by oxidizing copper metal or reducing sulfur oxide copper(II) solutions, while CuO is obtained by pyrometallurgical methods to remove copper from ores. The substance is irritating to the eyes and respiratory tract. Inhalation of fumes may cause metal fume fever. Ingestion could cause effects on the kidneys and liver. The results may be delayed.

Hydrothermal synthesis and sintering of ultrafine CeO2 powders

What is CeO2?Nanocrystalline cerium(IV) oxide (CeO2) powders were prepared by heating solutions of cerium(IV) salts in the presence of urea under hydrothermal conditions at 120° to 180°C. The effects of urea concentration and hydrothermal treatment temperature on the morphology and crystallite size of the synthesized particles were investigated. The synthesized particles were angular, ultrafine CeO2 with a cubic fluorite structure. Their crystallite size decreased from 20 to 10 nm with increasin
