Do You understand How to Make Graphite By Graphite Producer?

Maybe you have heard of Graphite Crucible，which is made of graphite. That's for confident. But just how much do you realize about the machining of graphite?

Let us talk concerning the graphite purification technique. To be distinct, graphite purification，can be divided into two approaches which could be integrated chemical purification and physical purification.

Now, let’s say one thing about chemical purification, which belongs to Graphite Machining. Typically speaking, chemical purification can use the nature on the graphite’s acid resistance, alkali resistance and anti-corrosion. We are able to use acid and alkali to do treatment for graphite concentrated ore. As a result, we can make impurities dissolve. Soon after that, we can wash all of the impurities away. In this way, we are able to improve concentrate ore’s grade. By utilizing the technique of chemical purification, we can get grade 99% of high carbon graphite. Electric Discharge Machining may also be utilized.

However, there are various techniques for chemical purification, the approach which we most broadly use may be sodium hydroxide high-temperature melting method. Graphite Producer can give us a lot more particulars.

As for the basic principle of chemical purification, when it truly is under the condition of high temperature which can be more than five hundred degrees, the graphite’s impurities (which primarily belong towards the silicate minerals) can react with caustic soda that is referred to as NaOH. Within this way, we are able to make them produce water soluble reactants. At the same time, we are able to use water to leach reaction materials. As a result, we can eliminate a part of the impurities. As for another a part of impurities, such as iron oxides, we can use alkali fusion and HCl to finish neutralization. In this way, we are able to make them to generate ferric chloride which can be soluble to water. If we use water to wash such sort of impurities, they are able to all be removed.

The equipments making use of Alkali fusion may be mostly divided into anchored mixer, melting furnace, spiral mixer, V type washing tank and so on. By the way, the recovery rate might be eighty 5 to ninety percent. And we have to finish investment with one particular hundred and fifty thousand to two hundred thousand yuan. As all of us know, though the process is more advanced, but you can find also some disadvantages. As an example, we need to consume a sizable quantity of water, the loss of graphite is significantly much more, the productivity is low, large quantity of alkali consumption and emissions of waste pollution for the environment.
