As one of the most widely distributed minerals on the earth's surface, quartz, mainly composed of SiO2, is a very stable resource in terms of physical and chemical properties. Quartz glass generally has good light transmission, high-temperature resistance, corrosion resistance, electrical insulation, etc., so it is also widely used in high-tech product industries that require high temperature, corrosion resistance, light transmission, wave filtering, and other production process environments. Quartz rods are one of the quartz products, which are briefly introduced below.

The following is a list of contents:

• Classification of quartz rods according to purity

• Physical characteristics of quartz rods

• The use of quartz rods in the laboratory

Classification of quartz rods according to purity

The purity of quartz rods depends on the raw materials, the purity of high-purity raw materials such as silicon tetrachloride can reach 99.9999%, which is mainly used in the production of optical fiber; the purity of high-quality natural quartz can reach 99.99%, which is used in the semiconductor industry; the purity of common quartz rods produced with high-quality natural quartz is around 99.9%, which is used in the production of high-intensity electric light sources.

Physical characteristics of quartz rods

The coefficient of thermal expansion of quartz rod is very small, only 1/10-1/20 of glass, has a high resistance to rapid heat and cold, bright quartz rod in the electric furnace at 1100 ℃ scorching for 15 minutes, and then put into cold water for repeated experiments will not crack, its softening point temperature of about 1730 ℃, the continued use of the temperature of 1100-1200 ℃, the highest short time use temperature of 1450 ℃. Because it has the characteristics of high purity, high-temperature resistance, and low coefficient of thermal expansion, it is commonly used in the pressure bridge bar of single-ended halogen lamps, fiber optic lighting, quartz fiber manufacturing, semiconductor silicon wafer processing, etc.

The use of quartz rods in the laboratory

Quartz rods are mostly used in the laboratory to stir the liquid without damaging our hands or the test liquid itself, so they are used more often, and glass rods can be divided into many kinds according to the different materials, quartz glass rods are one of them, and it has many roles. First, it can make the heat evenly dispersed. Secondly, it can transfer liquid and solid. Thirdly, it can be used to divert liquid in cases such as filtration. Fourth, it can be used for stirring in the case of dissolution, evaporation, etc. Fifth, it can be used to initiate reactions, such as igniting red phosphorus.

There are the following precautions for using quartz glass rods in the laboratory.

First, stir in one direction when stirring (clockwise or counterclockwise is fine). Second, do not stir too hard, so as not to break the glass rod or container (such as beakers, etc.). Third, stirring does not collide with the wall of the container, or the bottom of the container, do not make a loud noise.

In recent years, the application of quartz glass has gradually become common. To ensure the quality of quartz products, the company and the product supervision department should keep up with the times, do sufficient risk analysis, improve inspection standards, and finally improve product quality and ensure product safety for people to use.
