What is Silicon Dioxide? Si02 is the chemical name ofsilicon dioxide: silicon dioxide is an acidic oxide and a solid at normal temperatures. Silicon dioxide is insoluble in water and acid but soluble in hydrofluoric acid and hot concentrated phosphoric acid and can act with molten alkalis. Silicon dioxide is widely used, mainly for making glass, water glass, pottery, enamel, etc. Pure natural silicon dioxide crystal is a hard, brittle, insoluble, colorless, and transparent solid, and It is often used to manufacture optical instruments, etc. Silicon Dioxide is widely found in nature and forms rocks with other minerals. Natural Silicon Dioxide is called Silicon Dioxide, which accounts for about 12% of the mass of the earth's crust. It exists in crystalline and amorphous forms. Quartz crystal is crystalline silicon dioxide with different crystal forms and colors. The colorless and transparent crystal in quartz is usually called crystal. The crystal with a colored ring, band, or layer is called agate (containing impurities).
Preparation of Silicon Dioxide Hydrolysis precipitation method is a method formed based on the sol-gel method, which is different from the sol-gel method in that the pH value of the solution is adjusted by acid or alkali to make it and precipitate directly. Hydrolysis of methyl orthoSilicon Dioxidete in alcohol medium is catalyzed by ammonia to produce condensed product nano Silicon Dioxide, which is modified in situ by hexamethyldisilazane to prepare hydrophobic nano Silicon Dioxide. When the water temperature is 20 ℃, water, hexamethyldisilazane, When the molar ratio of ammonia and methyl orthoSilicon Dioxidete is 3.55:0.65:0.36:1, the amount of surfactant and flocculant is appropriate, the stirring reaction time is two h. The aging time is four h, the specific surface area is large, the average particle size is small, and the particle size distribution is narrow.
Role of Silicon Dioxide Sometimes it can be used as a food powder additive to prevent caking. Silicon Dioxide can make glass, electronic instruments, handicrafts, and refractory materials, which are important consumables for scientific research and development. Silicon Dioxide with low purity can be used to make cups and plates and can also be used as tableware and tea sets due to its high-temperature resistance.
Price of Silicon Dioxide Silicon Dioxide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Silicon Dioxide. A large amount of large amount will be lower. The price of Silicon Dioxide can be found on our company's official website.
