A crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot. Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and other metals. Quartz crucible has the advantages of high purity ,high temperature resistance, with big size ,good thermal insulation, economization on energy ,quality stability etc. Fused quartz crucibles are used in the manufacture of silicon metal for semiconductor wafer applications and polysilicon. In order to produce high quality wafers, starting materials are added to a crucible heated to high temperatures and pulled from the melt as a single crystal. Fused Quartz is one of the few materials that can combine the high purity and high temperature properties required for this process. GW offers graphite crucibles & Ceramics (Quartz) crucibles in different sizes and types. Whenever you need crucibles, just feel free to contact us, and we will reply you in a shortest time.

Graphite blocks.
The term "cover block" can have different meanings depending on the context in which it is used. In various fields, a "cover block" refers to different things. Construction and Civil Engineering: In the construction industry, a cover block is a small piece of material, often made of concrete, that is used to maintain a specified distance between the reinforcing steel bars (rebar) and the outer surface of a concrete structure. This distance, known as the "cover," is crucial for the durability and strength of the structure. Cover blocks are placed on the rebar before concrete is poured to ensure the correct spacing and to protect the rebar from corrosion. SPECIFICATION: Shape Square Color Grey Size Available in various sizes and for multiple shapes Design Hollow Keep the details as in the products details.

Graphite block is made of domestic petroleum coke, with carbon content above 99%. We have vibrated molded and isotropic graphite block. They are widely used in such fields as mechanical , electronics, chemical industry and other new industries. We can machine to specific shapes according to customers' requirements.
Molded graphite Molded graphite materials we supplied are divided into two series: fs series /fb series . They have high anisotropy. The materials provide extremely wide characteristics such as mechanical strength, friction and conductivity, which can be further enhanced by impregnation with resins or metals. Special materials can be processed by pressing components directly close to final sizes. The press-to-size-technology reduces the cost of machining in large quantities. Wooden box
Graphite crucible is an indispensable consumable part in the production of vacuum aluminized film. Vacuum aluminization has very strict requirements on the quality of graphite crucible. The quality of graphite crucible will directly affect the production quality and production cost of aluminized film.Our graphite crucible â??s density reach 1,9g/cm3. It greatly improves the oxidation resistance and service life of the crucible without cracking, generally more than 25 times, up to 80 times. Size:120 *120; 120 *110; 135 *120 and special specifications can be made according to customer requirements. The company uses patent technology with intellectual property rights to treat graphite materials with anti-oxidation and anti-leakage, which greatly improves the oxidation resistance, bulk density, flexural and compressive strength of graphite crucibles, enhances corrosion resistance, hardness, reduces porosity and permeability, and greatly weakens molten aluminium and gaseous aluminium molecules. Anti-oxidation, non-overflow, non-cracking, non-aluminizing, good evaporation effect, long service life, the average use of furnace to 18,600 meters, coil 50-60 times, 24,000 meters, coil 40-50 times, production of 12,500 meters, coil, 10,000 meters, coil, 9000 meters, coil, 5000 meters, the number of coil stoves will also be greatly improved.

Graphite Paper, Sheet plate Description : Graphite paper and graphite plate: it is made of high carbon phosphorus graphite by chemical treatment and high temperature expansion rolling. It is the basic material for manufacturing various graphite seals. It is widely used in the dynamic and static seals of machines, pipes, pumps and valves in electric power, petroleum, chemical industry, instrument, machinery, diamond and other industries. It is an ideal new sealing material to replace traditional seals such as rubber, fluoroplastic and asbestos. With the acceleration of the upgrading of electronic products and the increasing demand for heat dissipation management of mini, high integration and high-performance electronic equipment, a new heat dissipation technology of electronic products, that is, a new heat dissipation solution of graphite material, has also been introduced. This new natural graphite solution uses graphite paper with high heat dissipation efficiency, small occupied space and light weight. It conducts heat evenly in both directions, eliminates "hot spot" areas, shields heat sources and components, and improves the performance of consumer electronic products.

Graphite paper is divided into l Flexible graphite paper l Ultra-thin graphite paper l Sealed graphite paper l Heat conductive graphite paper l Conductive graphite paper, etc. different kinds of graphite paper can play their due role in different industrial fields. The following two items shall be paid attention to when storing graphite paper: 1. Storage environment: graphite paper is suitable to be placed in a dry and flat place, and is not exposed to the sun to prevent extrusion and reduce collision in the production process; It has certain conductivity, so when it needs to be stored, it should be far away from the power wire. 2. Prevention of cracking: the graphite paper is very soft, and we can cut it according to requirements. In order not to break them during storage, it is not suitable for folding or bending and folding at a small angle. General graphite paper products are suitable for cutting into sheets, such as rolled into barrels or flat storage in the shape of A4 paper.
