Question:

Why import quartz tube (fused quartz tube) high accuracy, is the processing process there is a difference?

Why import quartz tube (fused quartz tube) high accuracy, is the processing process there is a difference?

Answer:

It is not made in China, most of which has low melting cost, large quantity production, and relatively high temperature resistant gas diffusion furnace with relatively good capacitance.
If you want the specification accuracy, the domestic also has done quite well, can you talk about the requirements?Must I import it?At present, photovoltaic, ah, semiconductor diffusion furnace and other domestic use can be the biggest difference is purity, domestic or not imported high purityI have imported Heraeus and Japan's price is domestic more than 2 times
Do not know the diameter of this ellipse, the domestic is 3/1000, it is not imported, small craft is the same, but there are still high-end difference, the domestic still can not catch upIf the experiment you require is so high, it's only imported
