05FAQ常见问题
FAQ常见问题
What quartz products does United Quartz Company manufacture?联合石英制品公司生产哪些石英产品？
We manufacture ten quartz product families: capillary rods, laser cavities, end caps, plates and wafers, custom components, labware, tubes, sputtering targets, wafer boats and crucibles — in transparent or opaque fused quartz, standard sizes or built to your drawing.
我们生产十大石英产品系列：毛细棒、激光腔体、端帽、石英片与晶圆、定制零件、实验室器皿、石英管、溅射靶材、石英舟与坩埚，透明与不透明熔融石英均可，标准规格或按图定制。
Where is your quartz factory located?工厂地址在哪里？
United Quartz Company's factory is in Pingming Industrial Zone, Donghai County, Lianyungang, Jiangsu, China. Donghai is known as China's crystal capital and is one of the country's largest quartz material and processing clusters. Factory visits are welcome by appointment.
联合石英制品公司工厂位于中国江苏省连云港市东海县平明工业园区。东海被誉为中国水晶之都，是全国最大的石英材料与加工集聚区之一，欢迎预约到厂参观。
Do you accept custom or OEM quartz orders?是否接受定制或代工订单？
Yes. We work build-to-print from STEP, IGES or PDF drawings, or from physical samples. Orders range from one-off prototypes to repeat volume production, with material grade, tolerances and surface finish per your specification.
支持。可按图纸或实物样品来图来样加工，从单件打样到批量返单均可，材料牌号、公差与表面处理按您的规格执行。
What is the difference between fused quartz and fused silica?熔融石英与合成石英有何区别？
Both are amorphous silicon dioxide (SiO₂). Fused quartz is typically melted from natural quartz crystal, while fused silica is produced synthetically and usually offers higher purity and deeper UV transmission. We supply the grade that fits your application and budget.
两者均为非晶态二氧化硅。熔融石英通常由天然水晶熔制而成；合成石英为化学合成工艺制备，纯度通常更高、深紫外透过更好。我们会按您的应用与预算推荐合适牌号。
What are the key properties of fused quartz?熔融石英有哪些关键特性？
Typical values: density 2.20 g/cm³, softening point about 1683 °C, annealing point about 1120 °C, thermal expansion about 0.55 × 10⁻⁶/K (excellent thermal-shock resistance), broad UV-to-IR transmission and high chemical purity. It resists most acids except hydrofluoric and hot phosphoric acid.
典型值：密度 2.20 克/立方厘米，软化点约 1683 摄氏度，退火点约 1120 摄氏度，热膨胀系数约 0.55 × 10⁻⁶/开尔文（抗热震性优异），紫外至红外宽波段透过，化学纯度高。除氢氟酸与热磷酸外耐大多数酸。
