Typically, fireclays have high alumina and silica levels such as flint clays ... Filter / Diffuser Spargers or diffusers are porous ceramics used to blow fine bubbles of a gas into a metal melt to ...

Crystalline silica is also used to make products such as glass, pottery, ceramics, bricks and artificial stone. Respirable crystalline silica consists of very small particles of silica (less than 10 ...

Nanoparticles of semiconductors (quantum dots) were theorized in the 1970s and initially created in the early 1980s. If semiconductor particles are made small enough, quantum effects come into play, ...

Diana Aga. His current work involves developing and evaluating silica based stationary phases for chromatographic separations and developing superficially porous organo-silica particles with radially ...

Templates are particles with bonds that enable the formation of certain forms and sizes. Sol-gel syntheses (production of a gel from powder-shaped materials) are wet-chemical processes for producing ...

This article details how the nanoflowsizer is used for continuous size monitoring of turbid titanium dioxide nanosuspensions.

Cosmic rays are particles from outer space that travel across the universe. They can be made by the sun, by other stars exploding, and even black holes. They move extremely fast, nearly the speed of ...

Substances can exist in three states of matter - solid, liquid and gas. All substances are made from particles, and the forces between the particles are different in solids, liquids and gases.

Particles can be atoms, molecules or ions. Particles behave differently in solids, liquids and gases. The particle model explains the differences between solids, liquids and gases. Changes of ...

you may want to consider what will be best for how you work in the kitchen — perhaps you’d prefer a heavy-duty wooden board or an easy to clean rubber non-porous plastic board. Whether you ...
