SiO2 (single crystal quartz)-1

PAM XIAMEN offers SiO2 (single crystal quartz).

Single crystal quartz wafer is an excellent substrate for microwave filters for wireless communication industries.

Conversion from the three-index system to the four as [u ‘ v ‘ w ‘ ] —> [u v t w] is accomplished by the following formulas:
           X-cut           (110), (-1-10) =  (11-20) or (22-40),               XRD 2theta is 36.56 or 77.73 degrees

           Y-cut  (100), (010) (0-10) = (10-10),(20-20) or (30-30),    XRD 2theta is 20.86,42.46,65.83 degrees

           Z-cut                  (001) = (0001),                                       XRD 2theta is 50.66 degree or 117.7 degrees
          ST-Cut,     a rotated Y-cut with rotation 42.5°
          AT-Cut,     a rotated Y-cut with rotation 35°15′
