How to distinguish quartz glass from ordinary glass
2021-09-17 16:02:05

In life, we often use all kinds of glass products, such as glass windows, glasses, glass sliding doors and so on. Glass products are both beautiful and practical. They can not only be loved by virtue of their crystal clear appearance, but also make full use of their hard and durable physical properties. In this article, we will introduce the difference between ordinary glass and quartz glass, and teach you how to simply distinguish quartz glass from ordinary glass.


quartz glass


1、 Difference between quartz glass and ordinary glass

The main components of ordinary glass are sodium silicate, silicon dioxide and calcium silicate.

Quartz glass is a special glass made of silica, with higher hardness and transparency.

Quartz glass has high temperature resistance, wear resistance and soothing reaction, while ordinary glass does not have these advantages.

2、 How to distinguish quartz glass from ordinary glass

The main difference between quartz glass and ordinary glass is heat resistance. Quartz glass can withstand very high temperature, while ordinary glass is easy to crack

The production cost of quartz glass is high, usually only in places with special performance requirements. Moreover, the appearance of quartz glass is not high! Therefore, it is generally difficult to see in the market.

3.1 silica.

Silica, chemical term, pure silica is colorless, solid at room temperature, chemical formula is SiO2, insoluble in water. Insoluble in acid, but soluble in hydrofluoric acid and hot concentrated phosphoric acid. It can act with molten bases. Crystalline silica and amorphous silica exist in nature. Silica is widely used for making glass, water glass, pottery, enamel, refractories, aerogel felt, ferrosilicon, molding sand, silicon and cement. In ancient times, silicon dioxide was also used to make glaze and carcass of porcelain. General stones are mainly composed of silica and calcium carbonate.

3.2 glass

Glass is an amorphous inorganic nonmetallic material, which is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials. Its main components are silica and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O · Cao · 6sio2. The main component is silicate double salt, which is an amorphous solid with irregular structure. It is widely used in buildings to isolate wind and light, and belongs to mixture. There are also colored glass mixed with oxides or salts of some metals to show color, and tempered glass prepared by physical or chemical methods. Some transparent plastics (such as polymethylmethacrylate) are sometimes called agricultural production system glass.

3.3 calcium silicate

Calcium silicate, also known as microporous calcium silicate and active calcium silicate, is a compound formed by calcination and melting of calcium oxide and silicon dioxide at high temperature. It is mainly used as building materials, thermal insulation materials, refractory materials, physical pigment and carrier of coatings, as well as filter aid, isodragon seaweed mud, candy polishing agent, gum powder, rice coating agent, suspending agent Analytical reagent, etc.
