New Type Rare-Earth Composite Oxide Solid Solution Ceramic Thermal Field brief Introduction

Thermal resistance system of crystal growth furnace is traditionally taken by multi-layer W-Mo material, normally multi-layer structure,though satisfy crystallising demand, thermal energy consumption serious loss.With crystal industry development in recent years, some ceramic fiber screen systems appeared, achieve better thermal resistance effect and obvious reducing thermal loss,some ceramic basic material ageing to bring down thermal resistance performance, thermal field collapse, free volatiles, etc. problems caused, customer feedback about crack, working life, atmospheric contamination of thermal field, etc. problems, serious influence production cost, quality, profit of high quality crystal, it is also the important problems the cystal growth furnace manufacturer eager to settle. In the oversea artificial crystal market, most of manufacturers has adopted the zirconia thermal field or one matched metal mateiral instead of W-Mo material.Fangming Company is concentrated on manufacturing super high-temp. ceramics and ceramic thermal field system, instead of fiber zirconia thermal field and traditional W-Mo screen thermal system, save energy 40%-45%,clients' satisfied Composite Oxide Solid Solution Ceramic Thermal Field.
Difference of Rare-Earth Composite Oxide Solid Solution Ceramic Thermal Field from others.

● Material treated by special technology, no activity at high-temp. state. Super high purity, working temp. higher than zirconia fiber product,safety working temp. is below 2650deg. composite multi-layer design is composed by high-temp. resisting layer and bubble ball layer, excellent thermal stability and thermal resisting performance, special technology make denaturation soild solution ageing brought down, then reach super long working life and anti-spelling performance, meantime avoid fiber material (from) over shrinkage,compress at high-temp.state, breakthroug performance ageing and down etc.defects caused by system attenuation after traditional thermal field works. It is new type super high-temp. solid solution ceramic material.Super low volatilization and excellent oxygen release performances of solid solution ceramics is unique one in the whole crystal growth thermal field materials home and aboard.

● Rare-Earth Composite Oxide Solid Solution Ceramic have super high melting point, low thermal conductivity performance, is super high-temp. maerial inVacuum environment, reducing atmosphere and electromagnetic induction furnace thermal field, do not react or corroded, keep stability and uniformity at long-term super high-temp.working environment.
