Abstract
The invention discloses an energy-saving method for quickly measuring the carbon content of graphite. The method is characterized by comprising the following steps of (A) weighing a test sample with the weight of M; (B) gasifying the test sample into powder through an injector, and heating the powder to decompose the powder into gas and solids; (C) heating the solids, and stopping heating until the residual solids do not contain black spots; (D) cooling to the room temperature, and weighing the residual solids, wherein the weight is m; and (E) dividing m and M to calculate the carbon content of the graphite. The invention provides the method for relatively precisely measuring the carbon content of the graphite.
Description
Technical field
The present invention relates to a kind of method of accurate measurement graphite carbon content.
Background technology
Graphite, as a kind of high energy crystal material with carbon element, is widely used in the industries such as atomic energy, automobile, spationautics, metallurgy, chemical industry, machinery.In order to ensure the quality of graphite, often need the carbon content measuring graphite.Need be put in high temperature furnace at high temperature calcination a period of time during current measurement graphite carbon content, then remaining solid residue is measured in cooling, and the insufficient precision measuring carbon content that easily causes of graphite burning is not high.
Summary of the invention
The present invention, in order to solve the problem, provides a kind of method more accurately measuring graphite carbon content.
Fast energy-saving measures a method for graphite carbon content, said method comprising the steps of:
A) weighing device is used to take the sample that weight is M;
B) by thrower, sample gas is changed into powder, this powder is heated simultaneously, powder de-agglomeration is become gas and solid;
C) be heated to remaining solid without black splotch, stop heating;
D) cool to room temperature, take out remaining solid and use weighing device to weigh, weight is m;
E) m and M is divided by calculates the carbon content of graphite.
Described steps A) and step D) in weighing device be ten thousand/balance.
Beneficial effect of the present invention is: use ten thousand/balance measuring accuracy can be brought up to 0.1mg, measuring accuracy is higher; Adopt thrower by powder, can make to decompose more fully during heating, measuring accuracy is higher.
Embodiment
Fast energy-saving measures a method for graphite carbon content, said method comprising the steps of:
A) ten thousand/balance is adopted to take the sample that weight is M;
B) by thrower, sample gas is changed into powder, this powder is heated simultaneously, powder de-agglomeration is become gas and solid;
C) be heated to remaining solid without black splotch, stop heating;
D) cool to room temperature, take out remaining solid and adopt ten thousand/balance to weigh, weight is m;
E) m and M is divided by calculates the carbon content of graphite.
Protection scope of the present invention is not limited thereto, and is anyly familiar with those skilled in the art in the technical scope that the present invention discloses, the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should define with claim is as the criterion.
