① NC-200 quartz weight uses a hydrogen oxygen flame to melt high-purity quartz sand, preparing quartz weight with good transparency and low bubble rate. Quartz weights can be melted to produce square weights and larger round weights, which are used as raw materials for producing quartz square pieces, quartz circular pieces, and quartz flanges. NC-200 is mainly used in semiconductors, solar energy, LED, and flat panel displays.
② NC-H00 is a quartz raw material produced by electric melting method. Has excellent physical properties, high purity and low hydroxyl groups, suitable for industrial high temperature and semiconductor high temperature use.
