Chromic Oxide Slurry
CP titanium was polished with a colloidal sitica suspension and chromic ox{de slurry under low and high pressures. The polisheti surfaces wer'e characterized by means of EI]MA and XPS. Irrespeetive of polishing pressure, colloidal silica suspension suecessfully created a mirror-Iike surface that was clean at EPMA level, However, XPS detected a small amount of silicon on the outermost surface. O...
متن کاملA Clean Production Process of Chromic Oxide
Chromic oxide is an important basic chemical and finds many applications including metallurgical materials, green pigments, construction materials, refractory materials and catalysts. Presently, the industrial production of chromic oxide generally employs two processes (Ding, 2003): one is the reduction of sodium dichromate with ammonia sulfate; the other is the thermal decomposition of chromic...
متن کاملL-arginine chlorination products inhibit endothelial nitric oxide production.
The myeloperoxidase-derived oxidant hypochlorous acid (HOCl) is thought to contribute to endothelial dysfunction, but the mechanisms underlying this inhibitory effect are unknown. The present study tested the hypothesis that HOCl and L-arginine (L-Arg) react to form novel compounds that adversely affect endothelial function by inhibiting nitric oxide (NO) formation. Using spectrophotometric tec...
متن کاملExperience with the chromic oxide method of fecal marking in metabolic balance investigations on humans.
In metabolic balance studies the assessment of the subject's state of balance is derived from estimates of the dietary intake and the excretion in the urine and feces of the constituent under investigation. It is relatively simple to measure the dietary and urinary components, but estimation of the fecal component is more liable to error because of difficulties in secturing a quantitative fecal...
متن کاملExretion of chromic oxide administered in paper to steers fed prairie hay.
T H E value of chromic oxide (chromium sesquioxide) as an indicator for estimating fecal output of sheep and cattle is dependent upon its concentration at a given sampling time providing the basis for estimating a standard recovery. However, chromic oxide excretion rate exhibits a diurnal variation (Hardison et al., 1959; Kane, Jacobson and Moore, 1952) which apparently precludes choosing a des...
