Opaque Fused Quartz Crucibles, Solar Grade Fused Quartz Crucibles, Opaque Quartz Crucible for Chemical Processing

  PL-A PL-C series of quartz crucible inner surface of the crystal, can get better DF rate (into crystal rate).
Applicable on: Monocrystalline silicon solar drawn.
High DF (into the crystal) rate: A direct impact on the performance of the quartz crucible into monocrystalline silicon crystal rate will fall off when the quartz crucible surface devitrification quartz crystal plates, and adhesion to the monocrystalline silicon monocrystalline silicon, thereby reducing the into the crystal rate. Our quartz crucible is not easy to produce devitrification, and has the following two characteristics:
1) small bubbles
2) purified by the inner surface of
PL-A PL-C series of quartz crucible with the ordinary use of the quartz crucible surface state

Second, the surface of the high purity: The raw materials we use high-purity quartz sand, washed under high clean environment and under strict management, reaches the inner surface of high purity, the specific values in the table below:
20μ M surface of the quartz crucible layer purity analysis value (ppm):
Al Ca Fe Na Ka Li Cu
9.2 0.6 0.4 0.3 0.3 0.3 <0.05
Quartz crucible surface purity (ng/cm2):

Al Ca Fe Na Ka Li Cu
0.00096 0.00193 0.00385 0.00000 0.00000 0.00000 0.00000

In addition, the PL-A series crucible using a crucible inner surface Movement the porphyritic crystallized technology, so that the devitrification sheet does not come off.
(Use PL-A PL-C Series crucible surface thickness data crucible of surface thickness data comparison)

Third, long life: To prevent the crystallization of the inner surface of the quartz devitrification Exfoliated technology, the devitrification sheet does not come off. Can be used for a long time.
