1、What is fused silica glass?

Fused quartz or fused silica is glass consisting of silica in amorphous (non-crystalline) form. It differs from traditional glasses on containing no other ingredients, which are typically added to glass to lower the melt temperature. Fused silica, therefore, has high working and melting temperatures.

2、What Kinds of Fused Silica material can available from UNI OPTICS?

There are many companies offer Fused Silica material like Corning, Heraeus, Schott, Nikon NIFS and Ohara. UNI OTPICS could make fused silica products according to the design by Coring 7980, 7979, 7978, Heraeus Spectrosil 200, HOQ310, Suprasil 300 and JGS2, JGS2, JGS3, etc.

3、What is fused silica glass used for?

Fused Silica, SiO2 Glass Properties. Fused silica is a noncrystalline (glass) form of silicon dioxide (quartz, sand). Typical of glasses, it lacks long range order in its atomic structure. Its highly cross linked three dimensional structure gives rise to its high use temperature and low thermal expansion coefficient.

4、Can you make glass from quartz?

First, a little background: Lab glass can withstand insane temperatures and chemical reactions because it's made of fused quartz. ... Instead, this stuff is virtually pure silica, aka quartz crystals—which means that to mold it into test tubes, you need incredibly high temperatures.

5、How is fused silica made?

Fused Silica (also known as Synthetic Fused Silica) is made from a silicon-rich chemical precursor, usually using a continuous flame hydrolysis process, which involves chemical gasification of silicon, oxidation of this gas to silicon dioxide, and thermal fusion of the resulting dust (although there are alternatives) .
