How to calculate the life of closed paste

The report was published in the Journal nature

Sealed paste is also have their own life, this life is not to say that all depends on the product itself, in the middle is also have a lot of myself after the maintenance of these effects, so for us, this is confined paste a test for us, in this test, we don't have a very high decided for sure,  I hope you can learn what you should learn from this article.

It is not clear how the alkali metals infiltrate the bricks, whether siphoning or inhalation in general, but the effects of the alkali metals on the bricks are well understood, including strength deterioration and volume expansion and plastic expansion that leads to graphitization.  The following is a detailed introduction of alkali metal erosion on the service life of carbon bricks.

1. Strength deterioration: According to the test of used carbon bricks and alkali metal erosion test of unused carbon brick samples in the laboratory, it is found that the strength of carbon bricks decreases sharply after being eroded by alkali metal.

2. Volume and plastic expansion: it is found that the volume of carbon brick samples expands after alkali metal erosion experiment. However, when the samples are corroded by alkali metal under different loads, it is found that the samples have different degrees of plastic deformation and form plastic bodies according to different loads.

3. Promote graphitization: The laboratory test of used carbon bricks found that the thermal conductivity of carbon bricks increased after being eroded by alkali metals, and the observation under the microscope found that there was graphite phase, so it was concluded that alkali metals could promote the so-called low temperature graphitization of carbon bricks.
