Quartz rods are a material made of high-purity quartz, which is widely used in many fields due to its excellent physical and chemical properties. What should we know before buying quartz rods?

The uses and application scenarios of quartz rods

Quartz rods have a variety of uses, and different application scenarios have different requirements for their characteristics and specifications. For example, in the laboratory, quartz rods can be used for heating, stirring and other operations, which need to have high temperature wear resistance and chemical stability; in the field of semiconductor manufacturing, quartz rods are used to make wafer carriers, etc., which require ultra-high purity and low hydroxyl content; in the field of lighting, quartz rods can be used to make high-power lighting equipment, which requires good high temperature resistance. Therefore, clarifying the use scenario of quartz rods is the first step in purchasing.

The material and purity of quartz rods

The material of the quartz rod is a key factor affecting its performance. Quartz rods with high purity have better corrosion resistance, high temperature resistance and optical properties. Generally speaking, the higher the silica (SiO _ 2) content of the quartz rod, the higher its purity and the better its performance. For example, the semiconductor industry usually requires the purity of the quartz rod to reach more than 4N (99.99%). In addition, the hydroxyl content of the quartz rod will also affect its performance. Quartz rods with low hydroxyl content can maintain better strength at high temperatures.

The size and shape of quartz rods

The size and shape of quartz rods should be selected according to specific needs. Common quartz rods are cylindrical, but other shapes are also available. Dimensions, including diameter, length, etc., need to be determined according to actual application scenarios. For example, small equipment used in laboratories may require thinner quartz rods, while equipment used in industrial production may require thicker quartz rods. In addition, the length of quartz rods will also affect their application range. For example, quartz rods used in optical fiber manufacturing usually require longer sizes.

Optical Properties of Quartz Rod

The optical properties of quartz rods are very important in certain applications. For example, in the fields of ultraviolet spectroscopy, sterilization equipment, and semiconductor manufacturing, quartz rods need to have good ultraviolet transmittance. In addition, the transparency of quartz rods is also critical, and high-transparency quartz rods can better meet the needs of optical applications.

Thermal Properties of Quartz Rod

The thermal properties of quartz rods include high temperature resistance, coefficient of thermal expansion, and resistance to thermal shock. Quartz rods are able to withstand higher temperatures, with short-term exposure temperatures up to 1300 ° C and long-term operating temperatures up to 1100 ° C. In addition, quartz rods have a low coefficient of thermal expansion, which means it does not expand or contract significantly when the temperature changes. Quartz rods also have excellent thermal shock resistance, enabling them to remain stable in environments with rapid temperature changes.

Mechanical properties of quartz rods

The mechanical properties of quartz rods include hardness, strength, and wear resistance. Quartz rods have high hardness and wear resistance, enabling them to remain stable in harsh physical environments. In some applications that require frequent friction or collisions, such as grinding equipment, the wear resistance of quartz rods is particularly important.

Quartz rod customization requirements

If the standard size quartz rod cannot meet the specific needs, you can consider customization. When customizing quartz rods, it is necessary to communicate with the supplier in detail the specific requirements of the product's size, shape, purity, optical characteristics, etc. Customized quartz rods are usually more expensive than standard products, but can better meet the needs of special applications.

Before buying quartz rod, you need to consider its use, material, size, optical properties, thermal properties, mechanical properties, price, customization requirements, and other factors. Only by fully understanding this knowledge can you choose quartz rod that suits your needs and ensure its best performance in practical applications.
