GB/T 5687.2-2007 Ferrochromium,silicochromium and nitrogen-bearing ferrochromium—Determination of silicon content—The perchloric acid dehydration gravimetric method
Abstract
This part of GB/T 5687 specifies the determination of silicon content by the dehydration weight method using perchloric acid. This part is applicable to the determination of silicon content in chromium iron, vacuum micro-carbon chromium iron, nitrided chromium iron, and silicon-chromium alloys. The determination range (mass fraction): 0.10% to 60.00%.
