Quartz, Fused Quartz, Fused Silica, What's the Difference

Sep 27, 2021Fused quartz and fused silica is glass consisting of fused silica in an amorphous solid, it has a non-crystalline form. It has very little impurities compared to other forms of glass that have materials added which lower the working temperature. Thus, absent the added impurities, fused quartz and fused silica have very high working temperatures

Making of fused quartz and fused silica

One that starts with high purity quartz, or other Silicon dioxide containing minerals that are fused using various heat sources. This Material class is termed fused quartz. The other is called fused silica and starts with gaseous silicon containing chemicals (e.g. SiCl4) that are burned in the presence of oxygen to form silicon dioxide.

Synthetic Fused Silica

Synthetic fused silica is far purer than fused quartz. This increased purity ensures higher ultraviolet transmission and freedom from striae or inclusions. The synthetic fused-silica materials used by MellesGriot are manufactured by flame hydrolysis to extremely high standards. The resultant material is colorless and non-crystalline,

It has very little impurities compared to other forms of glass that have materials added which lower the working temperature. Thus, absent the added impurities, fused quartz and fused silica have very high working temperatures

RP Photonics Encyclopedia

Fused silica is sometimes called fused quartz or quartz glass. However, it should be kept in mind that it is an amorphous material, while quartz is crystalline. (When lamps are said to have a quartz envelope, it is always fused silica; the same holds for most "quartz tubes".) Other common names are silica glass and vitreous silica.

Making of Fused Quartz and Fused Silica • QSI Quartz

Jan 15, 2021One that starts with high purity quartz, or other Silicon dioxide containing minerals that are fused using various heat sources. This Material class is termed fused quartz. The other is called fused silica and starts with gaseous silicon containing chemicals (e.g. SiCl4) that are burned in the presence of oxygen to form silicon dioxide.

Quartz vs. Fused Silica: What's the Difference?

Sep 08, 2021Fused Silica is an entirely synthetic material, and is technically the purest glass. It has the highest temperature characteristics of any glass, and it often begins as pure silicon gas. Because of the way fused silica is made, it has superior ultraviolet performance to natural quartz

Fused quartz

Fused quartz is produced by fusing (melting) high-purity silica sand, which consists of quartz crystals. There are four basic types of commercial silica glass: Type I is produced by induction melting natural quartz in a vacuum or an inert atmosphere. Type II is produced by fusing quartz crystal powder in a high-temperature flame.
