High purity Silica Oxide

Q: How to synthesize 100 nm sized silica?: TiO2 because of its activity is too large, easy to agglomerate, affect the performance of products, the commonly used methods are aqueous solution deposition drying method, sol-gel method, etc..

Q: How does silica naturally form?: Silica also called silica, chemical formula SiO. There are two kinds of crystalline silica and amorphous silica in nature. Crystalline silica is divided into three kinds: quartz, scale quartz and square quartz because of their different crystal structures.

Q: What effect does silica content have on cement properties?: Properties: SiO2, also called silica. Widely distributed in nature, such as quartz, quartz sand and so on. White or colorless, with a higher iron content is pale yellow. Density 2.2 ~ 2.66., melting point 1670 degrees (Lin Shiying); 1710 degrees centigrade (square quartz). Boiling point 2230 DEG C. Insoluble in water and acid (except hydrofluoric acid); particles can interact with molten and alkali groups. Used for making glass, water glass, pottery, enamel, refractory material, ferrosilicon, molding sand, silicon and so on.

Q: Calcium carbonate and silicon dioxide paper belts are dangerous wastes?: Calcium carbonate and silicon dioxide are non-toxic. So the bags that come into contact with them do not belong to hazardous wastes.

Q: What is the difference between silica and reactive silica?: Silica dust is very fine, the specific surface area of more than 100m2/g (automatic F-Sorb2400 BET nitrogen adsorption specific surface area tester), can be suspended in the air, if the long-term inhalation of dust containing silica,

Q: Is silica and white carbon a product?: And white carbon is a special silica. Belong to silica category.Fumed silica is prepared by gas phase method, precipitation method, gel method, etc..Silica includes white carbon black.

Q: Is expired colloidal silica available?: Colloidal silica (colloidal, silka), also known as sol silica (colloidal sol), molecular formula: SiO2 ? nH2O. You say "expired" colloidal silica, may be due to long-term storage or heating, resulting in aqueous colloidal molecules SiO2 - nH2O or in case of dehydration, electrolyte sol, the silica particles gathered each other to form a silicon gel, the molecular formula is n (SiO2), which will be impossible to restore the original shape, can not be reused.

Q: Is the main component of the diamond silica?: The main chemical component of diamond is silica.Diamond is a commonly known, the main as is a crystal glass, is man-made crystal glass cutting into a faceted diamond jewelry accessories, such as material more economical, while the visual effect and dazzing feeling like diamonds. Therefore, it is very popular with people, the diamond is generally used in the design of mid-range jewelry.As a result of the current global man-made crystal glass manufacturing site, located in the north and south sides of the Rhine, it is also called Rhine stone. Produced in northern Austria Swarovski most do drill, referred to as Austria drill. It attracts sunshine very much, the gloss is very good, and the south bank is called Czech diamond. The absorption of sunlight is not enough, luster is not as good as Austrian drilling. Most of our products are Austrian drilling, and a few of them are Czech diamond.

Q: What are the environmental hazards of silica?: Silicosis is an occupation disease, the incidence and severity of the content and content of silica dust in the air depends on the dust, and the contact time. Long silica dust content in high places, such as mining, foundry, sandblasting, ceramics, refractories and other places of work tend to suffer from the disease. Therefore, in these more dust workplaces, strict labor protection measures are adopted, and a variety of techniques and equipment are used to control the dust content in the workplace to ensure the health of the staff.

Q: How to solve the gel problem between silicone oil and white carbon?: Silica is a porous substance whose composition can be represented by SiO2 nH2O, where nH2O exists as a surface hydroxyl group. Soluble in caustic and hydrofluoric acid, insoluble in water, solvent and acid (except hydrofluoric acid). High temperature, non flammable, tasteless, odorless, and good electrical insulation.
