Chemical granulation processing method for quartz surface

A method for chemically and roughly treating a quartz surface overcomes the defects of the prior art in which the treatment to the quartz surface easily leads to damage and influences the size accuracy of the quartz product. The method is as below: at a normal temperature and a normal pressure, immersing a quartz product into a container filled with a treating fluid so as to undergo reaction after the surface of the quartz product is polished, taking out the quartz product after two-hour reaction, and immersing the quartz product into the treating fluid again so as to repeat the preceding reaction till the roughness Ra of the surface of the quartz product is equal to 1.5 micrometers to 4.5 micrometers after attachments on the surface of the quartz product is eliminated with deionized water. The treatment process has reasonable design, involves simple devices and is easy to be operated, and the obtained quartz product has uniform surface roughness which is free from the influence of the shape. During the participation in the CVD reaction, the crazing and the shedding of a deposited film on the quartz surface is effectively reduced so as to reduce the possibility of pollution to the reaction cavity, to remarkably improve the finished product rate and the production efficiency, and then further to prolong the service life of the quartz product, save time, reduce consumption and reduce production cost.
