Characteristics and applications of high-purity graphite crucible

Graphite crucibles can be divided into two categories: machined graphite crucibles and clay graphite crucible. CFCCARBON LTD can produce both kinds of the graphite crucibles with large amount, stable and reliable quality. Machined graphite crucibles, also known as high purity graphite crucibles. Its produced/ machined from raw graphite material blocks or rods. In this article, we will introduce the Characteristics and applications of high-purity graphite crucible.

Features
High purity graphite crucible, the main feature is resistant to more than 2000 degrees Celsius temperature. Its chemical composition is almost all C, from 99% to 99.999999% have different uses, mainly used for melting high purity silicon and insoluble carbon refractory metals and as ultra- High-temperature heating elements.High-purity graphite crucible has excellent thermal stability;
High-purity graphite crucible has excellent corrosion resistance, impact resistance function, so to ensure product quality and reliability;
High purity graphite crucible has excellent resistance to acid, alkali.
High purity graphite crucible has excellent heat conductivity: can greatly shorten the melting time, saving energy;
With good neutron deceleration performance, act the first time as a slowdown agent for atomic reactors, graphite reactor is currently used as an atomic reactor mostly. The decelerating material in the nuclear reactor used as a power source should have high melting point, stable and corrosion resistance.

The main applications:
The uses of graphite crucible is, non-ferrous metal casting, characterized by the use of a long time, fast thermal conductivity.
Used in auto parts, electronics and new materials industry, graphite crucible is melting and holding non-ferrous metals and new materials, high-temperature containers.
Can also be used for non-ferrous metals and new materials’s refining and purification.
To help environmental protection, the international community to improve the light weight of metal products in industrial products.
So aluminum, magnesium, zinc and its alloys are widely used in the production of automobiles, motorcycles and electronic accessory products. Such as die-casting production of automobile and motorcycle wheels, engine cylinder head, brakes, air filters, pistons, radiators, steering wheel skeleton and electronic products such as mobile phone shell.
High-purity graphite crucible is widely used in experiments and metal smelting, high-purity graphite crucible material selection of special high-purity, high-strength, high-density graphite material; After high-precision CNC machining equipment, can process high-purity graphite crucible, graphite casting crucible , Graphite oil tank, pull the tube, pull-tab, pull the rods, such as graphite mold products.
High purity graphite crucible for the precious metal smelting selected special graphite material, can make high-purity graphite crucible products than the usual material products with the degree of more than 2 times, the use of longer life, more can withstand more than 2000 ℃ high temperature!

Good reputation, reliable quality, best service and high technologies are our eternal objectives!

Hope we can be your partners soon. We will serve you with our quality products and top technologies and benefit each other.
