1、The theory of graphite heat field of monocrystalline silicon, which involves physics, chemistry and geometry, is formulated by researchers after many years of repeated textual research and experience summary.

2、The graphite heat field usually use vibrated graphite as the bottom plate, heat preservation cover and upper and lower cover. However, for heater, crucible, guide tube, support rod, and pot support, isostatic graphite is generally used for graphite heat field. This ensures the strength and purity of graphite crucible.

3、The graphite heat field is one of the important conditions for the crystallization of monocrystalline silicon. The gradient distribution of heat field directly determines whether the monocrystalline silicon can be pulled out and the quality of monocrystalline silicon. The quality of material of heat field directly affects the life of heat field.
