Background technology
Currently, equipment, technique that domestic silica crucible manufacturing enterprise uses are introduced at the beginning of being derived from the 70's of last century from Japan
, not only the degree of automation is not high for the technique, is more realized by artificial in entire production process, and raw material can only
Rely on the quartz sand of external import, production cost height, high energy consumption, product number of bubbles is more, the production cycle is long, service life is short,
Drawn monocrystalline silicon success rate is low.The fast development of photovoltaic industry and the progress of monocrystalline silicon production technology are to silica crucible big straight
More stringent requirements are proposed for the professional domains such as diameter, high-purity, bubble are few, Impurity Distribution is high uniformly, high temperature resistance is good.Therefore,
There is an urgent need to be improved to meet the market demand to the production of existing silica crucible.
Invention content
The object of the present invention is to provide a kind of preparation process of silica crucible, production cost is low, the period is short, saves energy
Consumption, and product number of bubbles is few, service life is long, and drawn monocrystalline silicon success rate is high.
