首饰行业用高纯石墨坩埚
石墨坩埚主要成份组成为天然鳞片石墨与粘结剂，主要用于黄金白银等贵金属的冶炼，单晶多晶行业的硅提纯。该石墨坩埚具有纯度高、极耐金属溶液侵蚀，使用寿命长久。
■所选石墨材料有以下特点：
1.高耐热性：耐火度及高，最高温度可达2000℃左右。
2.热稳定性：针对石墨坩埚急热急冷的使用条件，进行特别设计以保证产品质量的可靠性。
3.耐侵蚀性：均匀细密的基体设计，延缓了坩埚的受侵蚀度。
4.耐冲击性：石墨坩埚所能承受的热冲击强度极高，所以任何工艺处理都可以放心进行。
5.耐酸性：特殊材料的加入显著改善坩埚的品质，在耐酸化指标方面表现卓越，并大大地延长石墨坩埚的使用寿命。
6.高热传导性：高含量的固定碳保证了良好的热传导性，缩短溶解时间，并显著地降低了能耗。
7.金属污染的控制：材料成分的严格控制，保证了溶解时石墨坩埚对金属没有污染。
8.质量稳定性：高压成形法的制作技术工艺更充分地保证了质量的稳定性。
9.抗粘连性：因为石墨有不易与熔汤粘连的特性，熔汤的浸透和附粘少。
我公司可据用户的需求和图纸设计肯加工各种规格的石墨坩埚。
High Purity Graphite Crucible for Jewelry Industry
Main ingredients for graphite crucible are natural flake graphite and binder. Itmainly used in the smelting of precious metals such as gold and silver, single crystal polycrystalline silicon purification. This kind of graphite crucible is with high purity, highly erosion resistant of metal solution and service life is long.
The selected graphite material is with the following characteristics:
1. High heat resistance: fire resistance is very high, the maximum temperatures up to about 2000℃.
2. Thermal stability: graphite crucible for acute thermal quenching of the conditions of use, specifically designed to ensure the reliability of product quality.
3. Corrosion resistance: substrate of uniform fine design, slow down the corrosion of crucible.
4. Impact resistance: graphite crucible can bear high thermal shock strength, so any process can rest assured.
5.Acid resistance: joining special materials significantly improved quality of crucible, acid and indicators of performance, and greatly extend the service life of graphite crucible.
6. High heat conduction: high levels of fixed carbon ensures good thermal conductivity, it can shorten dissolved time, and significantly reduces energy consumption.
7. Metal pollution control: strict control of the material composition, it can guarantee that the graphite crucible has no pollution to the metal while being dissolved.
8. Quality stability: high pressure forming method of production technology to ensure the stability of the quality
9. Blocking resistance: for graphite has the characteristic of not easy blocking with molten soup and with less saturated and viscosity of molten soup.
Our company can design and machine all kind of dimension graphite crucible according to the requirements and drawings of customers.
