Is a kind of high purity quartz glass, uniformly dispersed, micron sized holes can produce good diffuse reflection, a small piece of NC-W00 products can effectively block all wavelengths of light from ultraviolet to infrared. The density of this material and transparent fused quartz is very close to the fire, it is the one and only after polishing, microstructure and smooth surface, so NC-W00 has good sealing performance, compared with other quartz, erosion of NC-W00 are more resistant to hydrogen fluoride acid.
