Monocrystalline silicon brick is a crystal with substantially complete lattice structure. Which is the raw material for producing monocrystalline silicon wafers.Different directions have different properties.Mono brick is a good semi-conducting material. The mono brick is a rod-shaped single crystal silicon grown from the melt by a Czochralski method or a suspension zone melting method in industrial production. Its main indicators are minority life, oxygen concentration and ect.
