熔融石英坩埚专业制造企业, (株)索拉赛拉(SOLAR CERA). Fused Silica Crucible Manufacturer, The World's Only Unique Technology, SOLAR CERA
The World's Only Unique
Fused Silica Crucible Manufacturer
 
     
   
     
  High purity Fused Silica Crucibles developed by us are internationally unique in that they are produced using high purity Fused Silica and our exclusive, special forming processes. They are applicable to very high temperature (1650℃) while they have very low thermal expansion coefficient. They are ideal for the production of multi(poly)-crystal ingots · wafers for solar cells. Fused Silica Crucibles are used in cutting edge fields with wide variety of applications.

폐사에서 개발한 고순도의 용융석영도가니(Fused Silica Crucible)는 고순도의 Fused Silica 원료를 (주)솔라세라 만의 독보적인 특수성형법으로 제조된 세계유일의 제품으로, 사용 가능 온도가 아주 높고(1650℃), 열팽창계수가 매우 낮은것이 특징으로, 태양전지용 다결정 잉곳(ingot) · 웨이퍼(wafer) 제조에 사용되어지며, 초-고품질을 위한 최첨단 분야에서 다각도로 이용되고 있습니다.
