The preparation of high-purity silica powder generally includes chemical synthesis and natural mineral purification
Edit:Lianyungang Oster Silicon Powder Co., Ltd.   PublicDate:2020-02-12

The preparation of high-purity silicon powder generally includes chemical synthesis and natural mineral purification. However, through long-term research, it has been found that chemical synthesis has high cost and low yield, which cannot meet the demand.

Using natural quartz minerals as raw materials to prepare ultrafine powders can not only meet market demand, but also better reduce the content of harmful impurities in the powder.

The raw materials for the production of high-purity ultra-fine silicon powder are veined quartz, quartzite, fused quartz and composite raw materials. The choice of raw materials is very important, because the quality of raw materials used in production will directly affect the length of the production process, the level of production costs, and the quality of the final product.

Example: When producing crystalline silicon powder, vein quartz with relatively pure texture (SiO2 content is generally ≥99.9%) is generally selected, while some surface pollution, quartzite and quartz conglomerate, which are easy to remove by ordinary chemical methods, are ignored. Of minerals. Quartzite and quartz conglomerate in some areas of our country are also very pure in texture. They are good raw materials for processing and producing high-purity and ultra-fine silicon powder, and their hardness is slightly softer than quartz and easy to process.

The above is the preparation of high-purity silica powder that the editor tells you generally including chemical synthesis and natural mineral purification. You can simply understand it. The content is for reference only. If you need to know about it, please contact our manufacturer.
