Introduction
Quartz crystals are widely used in a variety of frequency control components, such as oscillators, filters, and resonators. These frequency control components are essential components in modern communication and computing systems. In particular, quartz crystals are the most stable and reliable frequency control elements available today. They can be used to produce highly precise frequency reference for a variety of frequency measurements.
The stability and reliability of quartz crystals are largely dictated by the mechanical and elastic properties of the material used to construct them. A material with excellent mechanical and elastic properties is the widely used elastic alloy 3J60 (YB/T5255-1993). It has a very good fatigue resistance and is able to maintain a high elasticity over a wide range of temperature. In this paper, we will discuss the application of 3J60 in quartz crystals and its fabrication process.
Mechanical and Elastic Properties
The mechanical and elastic properties of 3J60 are presented in Table 1. Its elastic modulus and elastic limit are 1.9X105 MPa, and 0.6X105 MPa respectively. In addition, 3J60 also exhibits excellent fatigue resistance and a wide temperature range of -190°C to +240°C.
Fatigue Properties
The fatigue properties of 3J60 are shown in Table 2. It has a very good fatigue resistance, with an endurance limit of 0.75X105 MPa and an S-N curve of 20,000 bending cycles. Therefore, 3J60 is very suitable for use in quartz crystals fabrication.
Fabrication Process
In order to obtain the desired properties from the quartz crystals, it is important to properly control the fabrication process. This can be done using X-ray photoelectron spectrometer (XPS) analysis. In the XPS analysis, the sample surface is scanned to determine the chemical composition, surface layers, and the distribution of elements on the surface. This analysis will provide valuable information about the structure of the quartz crystals and can help in controlling its fabrication process.
Performance and Electrical Properties
The performance and electrical properties of 3J60 quartz crystals are summarized in Table 3. Its frequency stability and ageing properties are excellent, with an ageing rate of 0.07×1012/week. In addition, it has a low temperature coefficient of frequency, high overtone load, and very low driving power. These properties make the 3J60 quartz crystals ideal for use in frequency control components.
Potential Applications
The 3J60 elastomer is highly suitable for use in quartz crystals due to its excellent mechanical and elastic properties. This makes it possible to produce quartz crystals with very high frequency stability and low temperature coefficient of frequency. These properties make the 3J60 quartz crystals ideal for use in a variety of frequency control components, such as oscillators, filters, and resonators. In addition, these quartz crystals can also be used in the manufacture of precision microphones and other audio devices.
