Additive Manufacturing of Optical Quality Germania-Silica

We report a method for fabricating optical quality silica and silica-titania glasses by additive manufacturing, or 3D printing. Key to this success was the combination of sol-gel derived silica and silica-titania colloidal feedstocks, 3D direct ink writing (DIW) technology, and conventional glass thermal processing methods.

Manufacturing toolbox for porous silica is good news for

To increase resource efficiency and purity of products, silica materials with a pore size and porosity that is optimized for a specific raw material and separation process are needed. However, large-scale manufacturing of porous silica technology have so far been limited in the range of achievable pore sizes and porosities.

Properties, Production and Uses of Sodium Silicate

The production process of sodium silicate is based on batch-wise operations. Sodium silicate can be produced by dissolving silica in molten sodium carbonate. It can also be produced in a reactor, by treating a mixture of caustic soda , water and silica in the form of quartz sand with hot steam.

Wafer Manufacturing | How Are Semiconductors Made?

The first step in the manufacturing process is the actual production of the wafer. In this process, purified polycrystalline silicon is heated to a molten liquid. A small piece of solid silicon is placed on the molten liquid. As the silicon is slowly pulled from the melt, the liquid cools to form a single crystal ingot.
