SiO2–这是振荡石英晶体基本材料的化学名称。公式表明它只由两种元素组成:硅和氧。我们还找到了SiO2自然界中的晶体形式:如天然水晶。这里，问题出现了:

真的水晶是用来生产振荡石英晶体的吗？

让我们仔细看看石英生产的第一步:

真正的岩石晶体曾经形成石英晶体的基础。然而，为了经济地生产这些部件，需要高纯度的水晶。在石英生产的初期，使用的是真正的岩石晶体，因此，根据其纯度由人工检查和分类。然而，这种形式的水晶在自然界中很少出现。

为了满足石英材料的质量要求，现在石英晶体是在所谓的“高压釜”中人工生产的。“高压釜根据水热合成原理工作”，我们的产品经理解释道。破碎的晶体碎片溶解在碱性溶剂中。因此，晶体可以受控的方式生长。“高压灭菌器是密封的，加热温度可达350°C至400°C，工作压力约为1500bar”，weier说。优势？人造晶体有规则的二氧化硅晶格2–高质量石英晶体的良好条件。ECLIPTEK CRYSTAL如何生长?

高压釜的下部，即压力容器，装有水、矿化剂添加剂和SiO2。所谓的“籽晶”被放置在上部。“在高压釜中，温度上升。它是从底部加热的，所以上下腔室之间有温差。溶解在较低区域的部分沉淀在晶种上。增长率由温度和压力决定，”产品经理描述道。根据这些数值，石英每天可以生长0.2至1毫米。增长越慢，结果的质量越高。

高压釜从底部加热。

大约40到80天后,“阿尔法”压电石英晶体就形成了，它甚至可以重达几公斤。在下一步中，从石英晶片上切割出单独的坯件。这里，必须考虑不同的切割角度。在此过程中，还会切下籽晶，并再次用于高压釜中的石英生产。

阿尔法晶体产生需要40到80天。

SiO2– this is the chemical name of the base material for oscillating quartz crystals. The formula shows that it is composed of only two elements: silicon and oxygen. We also find SiO2in its crystalline form in the nature: as natural rock crystals. Here, the question arises:

Are real rock crystals used for production of oscillating quartz crystals?

Let’s take a closer look at the first steps in the quartz production:

Real rock crystals once formed the basis of quartz crystals. However, for the economic production of the components, highly pure rock crystals are needed. At the beginning of quartz production, real rock crystals were used and, therefore, examined and sorted by hand according to their purity. In this form, however, rock crystals are rarely available in nature.

The artificial quartz production

In order to meet the quality requirements for the quartz material, quartz crystals are nowadays produced artificially in so-called ‘autoclaves’. “The autoclaves work according to the principle of hydrothermal synthesis”, explains our Product Manager . Broken crystal fragments are dissolved in an alkaline solvent. Thus, crystals can be grown in a controlled manner. “The autoclave is sealed hermetically and is heating up to temperatures of 350 °C to 400 °C. It works with pressures around 1500 bar”, says Wei?er. The advantage? Artificial crystals have a regular lattice of SiO2– a good condition for high-quality quartz crystals.

How the quartz crystal grows

The lower part of the autoclave, the pressure vessel, is filled with water, mineralizer additives and SiO2. So-called ‘seed crystals’ are placed in the upper part. “In the autoclave, the temperature rises. It is heated from the bottom, so that there is a temperature difference between the lower and upper chambers. The parts dissolved in the lower area settle on the seed crystals. The growth rate is determined by temperature and pressure,” describes the product manager. Depending on the values, a growth of the quartz of 0.2 to 1 mm per day is possible. The slower the growth, the higher the quality of the result.

After about 40 to 80 days, the ‘alpha’ crystal is produced, which can even weigh several kilos. In the next step, individual blanks are cut out of the quartz wafers. Here, different cutting angles have to be considered. The seedling is also cut out in the process and is used again for quartz production in the autoclave.
