lead sulfate造句

• The pigment known as lemon yellow often contained barium chromate mixed with lead sulfate.
• Lead Sulfate is a white crystal or powder.
• The blanc fixe acts as a seed crystal for the lead to lead sulfate reaction.
• An example is a change from galena ( lead sulfide ) to anglesite ( lead sulfate ).
• "' Anglesite "'is a lead sulfate mineral with the chemical formula PbSO 4.
• Sulfation occurs when the electrodes become coated with a hard layer of lead sulfate which weakens the battery.
• "' Leadhillite "'is a lead sulfate carbonate hydroxide mineral, often associated with anglesite.
• The curing process caused the paste to change to a mixture of lead sulfates which adhered to the lead plate.
• Within the weathering or oxidation zone galena alters to anglesite ( lead sulfate ) or cerussite ( lead carbonate ).
• During normal lead-acid battery operation, lead sulfate crystals grow on the negative electrode during discharging and dissolve again during charging.
• Normal lead acid battery operation sees small lead sulfate crystals growing on the negative electrode during discharging and dissolving back into the electrolyte during charging.
• :The lead sulfate probably did nothing and was probably not there, but the sulfuric acid would have reacted with the bicarb, to release Carbon dioxide.
• "' Grandreefite "'is a rare secondary lead sulfate-fluoride mineral with a general chemical formula, Pb 2 SO 4 F 2.
• Patented by Charles Francis Brush in 1876, the depressions in a ribbed or grooved sheet of lead were filled with pulverized lead oxychloride ( later also lead sulfate ).
• This is a process in which lead sulfate forms on the plates, and during charge is converted to lead dioxide ( positive plate ) and pure lead ( negative plate ).
• This is particularly the case when the battery is forced to perform at very high rates of discharge, which tends to promote lead sulfate crystal growth on the surface of the electrode.
• While getting a new car battery, I watched them clean a lot of white, lead sulfate corrosion from the terminals by pouring some baking soda mixed with warm water on it.
• "' Lanarkite "'is a mineral, a form of lead sulfate with formula Pb 2 ( SO 4 ) O . It was originally found at Leadhills in the Scottish county of Lanarkshire, hence the name.
• :Note that battery acid ( if it came out of a battery, as opposed to a refill bottle ) contains large amounts of lead sulfate, and is therefore highly toxic even after the acidity has been neutralized .-- talk ) 02 : 00, 27 February 2008 ( UTC)
• At moderate rates of discharge, the lead sulfate crystals grow throughout the cross section of the electrode plate ( which has a sponge-like consistency ) since the electrolyte ( dilute sulfuric acid ) is drawn diffused through the body of the electrode to allow the reaction can take place throughout the plate.
