以高纯钨粉为原料，通过等静压和烧结成型，烧结温度2300℃，然后再在轧机上进行轧制，制备出超高纯钨板。钨板制备完成后，线切割取样10*10*T（避开边缘20mm），然后六面磨光，超声波清洗烘干后，双层真空包装，然后寄给相应的第三方检测机构进行GDMS的检测。

Ultra-high purity tungsten plate was prepared by isostatic pressing and sintering with high purity tungsten powder at 2300℃ and then rolling on a rolling mill. After the tungsten plate was prepared, a sample of 10*10*T was taken by wire cutting (avoiding the edge by 20mm), and then six sides were polished. After ultrasonic cleaning and drying, double-layer vacuum packaging was carried out, and then sent to the corresponding third-party testing institutions for GDMS detection.
