The Graphite Material of Photovoltaic Industry

As we know, graphite is widely applied , As technology has improved,high density, high strength, good isotropic graphite has become more and more useful, which is iso-graphite, iso-graphite is widely used in solar photovoltaic industry.

In the monocrystal or polycrystalline furnace, the most common products are graphite crucible, heating element, guide cylinder, graphite tray, heat shield an so on.

  Graphite hot zone of guide cylinder

  Graphite hot zone of heating element

  Polycrystalline graphite sabot

  Polycrystalline graphite parts

Graphite materials have excellent characteristics that other metal materials can not be replaced in solar photovoltaic industry, such as heating evenly, good earthquake-resistance,and prolong machinery  life-cycle at the same time.

Whether at home or abroad, the isostatic pressure graphite is preferable for graphite hot zone.Which is an important materials.

Graphite Plate Is Better Material In Vacuum Furnace 

Tough Graphite Mold Market 2016

Graphite Plate Is Better Material In Vacuum Furnace

Graphite plates used for vacuum furnace, which is generally resistant to 2,000 degrees celsius, the other materials are not up to such a high temperature.and graphite is the most electrically conductive non-metallic minerals in the nature, its temperature can reach 30 degrees celsius temperatures, and it is the best conductive material, so it's applied to vacuum furnace、heat treatment furnace. Ceramics can also be resistant to several thousand degrees, but the ceramics are not non-conductive, so they are just used to make protective sleeve, not the heating rods.

Graphite plates used in vacuum furnace,if they are different materials selected, its life is different, oxidation time will be also different. in general, poor material of graphite rod, after heating, the oxidation will speed and be not durable, and then the surface oxidised, it will become broken easily. so high density graphite plate is the best choice. as top graphite plates supplier, XRD Graphite Manufacturing Co.,Ltd offers high purity graphite、high density graphite and high strength graphite.

Tough Graphite Mold Market 2016

How To Prolong The Service-life Of Graphite Plate

Tough Graphite Mold Market 2016

Now, with the global scarcity of resources, raw material price increases much more than before, so the cost of graphite mold rises too. some of graphite molds suppliers can not afford the cost and "close the door". some large companies have started new ideas of graphite mold market to find a new way.

Graphite mold enterprises are facing heavy pressure:

1、The rapid rise in prices of raw materials make graphite mold rises price at almost months or even one or two months, some large graphite mold companies had to cut profits.

2、Due to the impact of national policies,huge domestic graphite mold industry is also facing increasingly intense competition.

3、From the consumer in terms of market players, consumers have become more rational than before, a very sought-after price promotion also has lost the power.

Cooperation and competition of graphite mold suppliers:

For graphite mold companies, they must identify the market position、customer orientation、brand positioning, establish a unique brand personality, enhance their competitiveness and occupy and expand the market.

In addition, the agreement between the future market needs related companies coexist to form groups to occupy the market. This requires companies to be good to share the benefits with others, so that companies can win-win.

Graphite mold market forms a new pattern of brand segmentation:

Brand integration, capital operation, the enterprise alliance is the more active,these are notable feature of graphite mold industry this year, such as graphite molds for silver、graphite molds for copper、graphite molds for glass etc.the industry reshuffle soon, the competition will force the brands companies segment customers in the market, new pattern segment formed in the brand.

How To Prolong The Service-life Of Graphite Plate

Graphite plate is widely used in many industries, so the maintenance is importmant for customers. as one of top graphite plates suppliers-XRD graphite makes a few considerations and advices as follows:

1)The amount of current increased to Graphite plate, the higher temperature of the appearance for graphite plate. It recommends to use as small as possible load density (power).

2)Parallel connection for the grpahite plates, avoiding to be broken for the rapid increase of resistor.  

3)After the graphite plate heated in the air, the appearance of graphite plate will constitute a dense silicon oxide film, playing the effect of extending service-life.

4)When graphite plates used continuously, resistor need to be added slowly to delay service-life.

5)the higher temperature,the shorter service-life for graphite plates. in the furnace of 1400℃ or above,oxidation rate will accelerate to shortened the service-life. so try not to let the temperature of the graphite plate surface too high when used in the process.
