The case of graphite boat is harmful to the proportion of the surface layer

The harm of the shape of the graphite boat to the surface layer of the surface layer will use the new graphite boat and the use of the old graphite boat for more than three years to saturate the coating on the surface layer of the PECVD surface. The flat surface of the new graphite boat is good, and the graphite boat has the same conductivity. The plastic membrane molecular formula can be uniformly accumulated on the surface of the single crystal silicon wafer, and the uniformity between the pieces is higher.After the new graphite boat is saturated, there are still some plasma accumulated on the graphite boat when the accumulation is accumulated. When the number of running times is less than thirty times, as the number of running times increases, the plasma accumulated on the graphite boat decreases. Essence After the number of running times exceeds thirty times, as the number of uses increases, the inner wall of the graphite tape and the single crystal silicon tablets touch the plast

Ballical graphite price about the use of graphite

1. The price of spherical graphite about graphite is: including bricks, disasters, disaster, linked powder, mold, mold and refractory material detergent. Two important changes in the refractory material industry are the application of magnesium carbon bricks in the application of steelmaking furnace lining and aluminum charcoal brick in the continuous casting. Graphite refractory materials, steel and other industries have close connections. Magnesium MGO-C in the world has been widely used for steelmaking and has become the traditional use of graphite. Aluminum carbon bricks are mainly used for continuous casting carbon resistance materials, and the flat flats are protected from plate blanking from pipelines and underwater nozzles. Ferry -resistant materials and related products produced by graphite and related products, such as 坩埚, distilled and similar plug nozzles, are also stable by metal penetration and erosion. Graphite products are widely used in the process of directly related

What are the key applications of graphite shells?

With the development of science and technology, graphite slowly turns into selected raw materials for mold production with its excellent physics and organic chemical characteristics. Graphite molds are generally used in various industries. Below I take the old iron to take a look at the key use of graphite mold!1. Rare metal forging and semi -continuous forging for graphite moldIn recent years, countries around the world have been marketing and promoting the situation of fusion metal materials and continuously (or semi -continuous) production and manufacturing bars or pipes. China has gradually selected this method at the level of copper, alloy copper, aluminum, aluminum alloy profiles. Artificial synthetic graphite is a continuous forging or semi -continuous forging as a rare metal. Manufacturing practice has proved that because of the selection of graphite mold shells, it has excellent thermal transmission performance (the heat transfer performance decided to condense the condensate

Introduce the asphalt rubber pendant penetration processing process of graphite board

The general operating process of graphite immersion is after being loaded into the product, first vacuum packaging (gas in the gas in the pores in the pores of the product) and then put it in the impregnation agent to submerge the product, then pressure it to the liquid level, so that Essence It is used for different intentions, and the standards of impregnation agent processing process are not thorough. Below, I will introduce the asphalt rubber mud impregnation processing process of graphite board in detail.The whole process of processing the processing technology of asphalt rubber -soaking small graphite board, electrode connector and its graphite anode board:First of all, the semi-finished processing surface of the graphite board was burn, and then put it into the product box and put it in the temperature of about 4 hours in the temperature of about 240-Soot. After the heat, the product is quickly installed into the impregnation tank with the iron frame (the immersion can be heate

What is the ultra -fine graphite powder used in industrial production

Today, the editor of Qingdao Risheng Graphite will tell you what the ultra -fine graphite powder has in industrial production, I hope to help everyone.

Graphite rotor action

The graphite rotor rotating nozzle is made of high-purity graphite. In addition to considering the need to disperse bubbles, the structure of the nozzle also utilizes the centrifugal force generated by stirring the aluminum alloy melt to evenly mix the melt into the nozzle with the horizontally sprayed gas, forming a gas/liquid flow to spray out, increasing the contact area and contact time between the bubbles and the aluminum alloy liquid, and improving the degassing and purification effect.Due to the characteristics of graphite such as self-lubrication, high temperature resistance, and corrosion resistance, graphite materials are made into graphite shaft sleeves, graphite sleeves, and other graphite processing parts with different specifications according to the use of different mechanical equipment. Our company has been engaged in the processing and manufacturing of graphite products in recent years. The most important characteristics of the processing of graphite shaft sleeves and

Application and Introduction of Graphite Pillars

The graphite column combines the wear resistance of copper alloy and the self-lubricating performance of solid graphite lubricant, making it unnecessary to refuel and maintain during use. The product is widely used for high load, intermittent or swinging movements, such as production lines for steam locomotives, water turbines, reservoir work/accident doors, plastic machinery, etc. According to the operating conditions used, various types of copper alloys can be provided.The main component of graphite column is graphite, and its performance is different from that of ordinary graphite1、 The production and processing technology characteristics of graphite pillars:1. High temperature resistance: Graphite is currently one of the most high-temperature resistant materials known. Its melting point is 3850 ℃± 50 ℃, and its boiling point reaches 4250 ℃. It is subjected to an ultra-high temperature arc at 7000 ℃ for 10 seconds, with the smallest loss of graphite, which is 0.8% by weight. From t

Carbon and graphite products

（1） Graphite electrodes are mainly made from petroleum coke and needle coke as raw materials, and coal tar pitch as a binder. They are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. They are conductors that release electrical energy in the form of an arc in an electric arc furnace to heat and melt the furnace material. According to their quality indicators, they can be divided into ordinary power, high power, and ultra-high power. Graphite electrodes include:(1) Ordinary power graphite electrode. Allowing the use of graphite electrodes with a current density below 17A/cm2, mainly used for ordinary power electric furnaces such as steelmaking, silicon smelting, and yellow phosphorus smelting.(2) Anti oxidation coated graphite electrode. A graphite electrode coated with an antioxidant protective layer on the surface forms a protective layer that is both conductive and resistant to high-temperature oxidation, reducing electrode consumption duri
