Lead tungstate crystal (PWO) has broad prospects in the fields of nuclear medicine and high-energy physics. my country has strong research and development capabilities.

Lead tungstate crystal, referred to as PWO, chemical formula PbWO4, colorless and transparent appearance, tetragonal crystal system, scheelite structure, is a new type of scintillation crystal. Lead tungstate crystal has the characteristics of high density, fast response speed, short radiation length, short light attenuation time, good resistance to radiation damage, non-deliquescing, and low cost.
