graphite expansion graphite environmental materials

The effect of expanding graphite on water pollution has a large number of research results. In terms of governing oil and organic pollution in the control of water bodies, expansion graphite is far more effective and economical than ordinary activated carbon now. But expansion graphite is inconvenient to transport and needs to be prepared at the application site. The preparation, use, recycling, and regeneration of expansion graphite environmental protection materia

High pure graphite

High pure graphite generally refers to graphite with carbon content of more than 99.99%. It can be divided into three types: coarse particle structure, fine particles structure, and ultra -fine particle structure in the tissue structure. In the furnace. The basic materials of the integrated circuit are mainly silicon single -crystal chips. The current growth process of silicon single crystal mainly adopts a direct pull (CZ) method. Other methods include the magnetic field direct pull method (MCZ), the area (FZ) method, and the double -yarm pull crystal method Law, the global electronic industry uses straight single -crystal silicon to account for 80% of the total amount of single crystal silicon. The graphite in the direct pull single crystal silicon furnace is consumables. Heating system. In 2005, China needed a straight silicon single -crystal furnace to use about 800 t.Another important purpose of high pure graphite is processed into various types, which are used to produce preciou

Graphite chloride roasting method

The chloride roasting method is to mix graphite with a certain reducing agent to bake at high temperature in specific equipment and atmosphere. The price in the material is transformed into a metal chloride with gas or condensed phase. Purified process.

The difference between flake graphite and expanded graphite

Flake graphite is a type of natural graphite that, after being extracted and purified, generally appears in the form of fish scales, hence it is called flake graphite. Expandable graphite refers to flake graphite that, after acid washing and intercalation treatment, expands by about 300 times compared to the previous graphite. It can be used as raw materials for coils and flexible graphite. Below, let me introduce in detail the differences between flake graphite and expandable graphite:1. The use of flake graphite is more extensive than that of expandable graphiteIn industrial production, flake graphite not only has the function of expandable graphite, but also has much better conductivity, thermal conductivity, smoothness, and so on than expandable graphite. So its practical use in industry is becoming increasingly widespread.2. The production processes of flake graphite and expandable graphite are differentFlake graphite is mainly made by mechanical damage and grinding. Expandable g

The rise of electric vehicles has led to rapid growth in demand for battery materials

With the increasing awareness of global environmental protection, electric vehicles are increasingly receiving attention and favor from people. And one of the most important components of electric vehicles, the battery, has become a popular product in the market. However, the popularity of electric vehicles will lead to a significant increase in demand for battery materials. How big is this market and what materials will become the mainstream?Firstly, the growth in demand for battery materials is evident. According to consulting firm Roskill, the global market size for battery raw materials in 2018 was approximately $25 billion, and it is expected to reach $70 billion by 2025. This growth will mainly come from demand growth in fields such as electric vehicles, energy storage systems, and renewable energy.Secondly, what are the main components of electric vehicle battery materials? Lithium, nickel, cobalt, manganese, aluminum and other metals are all used to varying degrees. Among them

Development of Expandable Graphite

Graphite crystal has a hexagonal network plane layered structure composed of carbon elements. The carbon atoms on the layer plane are bound by strong Covalent bond, while the layers are bound by Van der Waals force force. The binding is very weak, and the distance between layers is large. Therefore, under appropriate conditions, acid, alkali gold, salt and other chemicals can be inserted into the graphite layers, And combine with carbon atoms to form a new chemical phase - Graphite intercalation compound (GIC). When heated to an appropriate temperature, this interlayer compound can instantly and rapidly decompose, producing a large amount of gas, which makes graphite expand along the axis into a new worm like material, namely expanded graphite. This unexpanded Graphite intercalation compound is expandable graphite.Expandable graphite was first discovered by Schaufautl, a German. In 1841, Schaufautl soaked natural graphite in a mixture of concentrated HNO3 and concentrated H2SO4, and t
