SiO evaporation material, Si powder for SiO raw materials and the production method of SiO

摘要

It is the SiO evaporation material which features that the SiO or SiO evaporation material, or the gaseous hydrogen content which feature that gaseous hydrogen content is above 120ppm are above 150ppm, the occasion where it evaporates, to be possible, efficiently to form SiO steaming/evaporation covering to hasten membrane speed, it is possible SiO to the base substance. The occasion where SiO is produced by making the gaseous hydrogen content of the Si powders for these raw materials above 30ppm, it is possible, low and to hasten sublimation speed, it is possible at cost to produce in high efficiency. Because of this, to utilize wide-ranging the food, with transparency of the medical item and the medical supply etc as a production method of the evaporation material of the evaporation material of the packing material which possesses barrier characteristic or the electrode material for the lithium electric battery which possesses SiO steaming/evaporation covering it is possible the production method of SiO of this invention.
