Carbon is an element that can form into several different allotropes including graphite, diamond, and fullerite. Graphite is the most steady type of carbon and is the most well-known, as carbon naturally occurs as graphite under standard conditions. Graphite is generally known for its better conductivity and resistance for high heat and corrosion. This makes it a typical material in high heat, high-pressure circumstances in the aerospace, electrode, nuclear, energy, and military industries. Despite the fact that graphite can deal with extreme high-pressure circumstances effortlessly, it is really an exceptionally delicate, rough, and fragile material.
Owing to our quality centric organization, we are supplying the Isostatic High Density Graphite which raw materials are procuring from Japan & manufactured as per the international quality norms. It is highly reliable for a longer service life and appreciated by the clients for their excellent performance, wide industrial applications, smooth surface and high strength. We offer this product this within affordable price range and ensure timely delivery direct at the clients' premises. Moreover, these products are manufactured in accordance with the clients' exact specifications. Graphite Crucibles Grade Isostatic High Density offer high performance with good technical and economic effect. They are used in metallurgy, casting, chemical and (scientific) industry in general; they are also used to produce alloy tool steel melting and non-ferrous metal and alloy melting.
Graphite material is oxidised under heat in an air environment, so it is largely used in inert environments and vacuum applications such as in the manufacture of semiconductors and its also used by the nuclear industry. The grade Isostatic High Density material has similar properties to Boron Nitride material allowing for use at extreme temperatures (up to 2700°C), in an inert atmosphere.
Maximum service temperature is 4100C, maximum inert atmosphere service temperature is 27000C.
Thermal spalling resistance: Extremely higher resistance to rapid heating and cooling with less spalling.
Erosion resistance: Extremely higher resistance to metal or flux erosion with its uniform and dense structure.
Thermal shock resistance: Higher cold and hot strengths which assure safety handling.
Oxidation resistance: The improved base material and the newly developed special glaze provide the excellent oxidation resistance and remarkably longer service life.
Higher thermal conductivity: The high percentage of fixed carbon makes the material the higher thermal conduction which ensures shorter melting time and save fuel consumption.
No metal contamination: The base material has been strictly selected so that hardly any metal contamination during melting operation.
Stable quality: The Cold Isostatic Press (CIP) shaping system and the substantial quality assurance system maintain stable product quality.
Graphite has many industrial applications in various natural or synthetic forms but he application for this grade is specific to industries and applications such as :
Reducers, particularly in the steel industry (blast coke furnaces)
Electrodes for the steel industry (electrical steel)
Moderators in nuclear reactors
Adsorbents in activated charcoal filter
Diamond Tool Pressure Sintering
Continuous Casting Dies for Aluminium, Copper and Brass
Crucibles and Sealing Rod
Semi Conductor applications
Solar Technology applications
Graphite machining can be done using the below five methods:
Venture Scientific® has tie-up with many Job Work offering companies who has manufacturing processes and a certified quality system allowing them to manufacture the most complex parts in complete compliance with your designs and requirements.
