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 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.

HJ-C Graphite Crucible Ceramic Cover High quality Graphite Crucible ceramic cover for melting furnace. 1. Thermal stability: According to the quench acute thermal using conditions of graphite crucible, we will specially design the production procedure, so as to ensure the reliability of product quality. 2. Corrosion resistance: Even and fine basic design will delay the erosion of crucible. 3. Impact resistance: Graphite crucible can bear high thermal impact, so any process can be carried out. 4. Acid resistance: The adding of special materials will greatly improve the quality of crucible, especially its index of acid resistance., and will prolong the service life of graphite crucible. 5. High heat Conduction: High content of fixed carbon ensures the good heat conduction, shorten the time of dissolution, and remarkably reduce the energy consumption. 6. Control of metal pollution: The component of material under strict control will ensure that graphite crucible will not pollute the metals when dissolving. 7. Quality stability: The process technology of forming under high pressure and quality guarantee system will fully ensure the stability of quality.
