摘要： A method and apparatus for detecting impurities in quartz sand. The apparatus comprises at least one light source; at least one light detector assembly; a transport device; and a signal processor that receives the at least one signal from the at least one light detector assembly. The method comprises moving the quartz sand; illuminating the quartz sand to excite luminescence emission from impurities; receiving luminescence emission from the impurity; generating at least one signal indicative of the excited luminescence emission from the impurity; and determining if the signal represents an impurity in quartz sand.

摘要： An opaque silica comprises silica and at least one second phase solid material. The at least one second phase solid material is essentially uniformly dispersed in the silica. A cut surface formed through the silica is free from surface defects since the at least one second phase solid material forms an opaque silica that is free from porosity.
