Advantages
①Tungsten molybdenum and zirconia, alumina bricks provide good heat preservation and low power;
②Protected with inert gas, there is less volatile matter, and the service life of the thermal field is significantly extended;
③The thermal field strut is upgraded to enhance the stability and thermal conductivity of the bottom, which increases the temperature gradient;
④Due to the fluidity of the melt, it's easy to observe the seeding crystal;
⑤The growth cycle is short, the energy consumption is low, and the material extraction rate is significantly improved;
⑥Loaded weight 125±25kg;
⑦One-button start, reducing manual intervention and facilitating large-scale production control;
⑧Optional thermal field and growth process;
⑨Long-term costs are relatively low.
