石英管

石英管（主に二酸化ケイ素、SiO2で構成）は高温で化学的安定性を示すが、これはいくつかの重要な要因に影響される。主な要因は以下の通り：1.温度 温度が上昇しても、石英管の化学的安定性は概ね一定である。高温(1100℃以上)では、石英管は格子歪みや相転移などの構造変化を起こす可能性がある。しかし、石英管は通常、大きな化学反応を起こすことなく、1400℃もの高温に耐えることができる。このため、石英管は、半導体製造や高温化学反応のような極端な温度を伴う産業用途で一般的に使用されている。2.雰囲気 石英管の安定性は、化学的雰囲気によって異なる。純[...]では

Vacuum laboratory quartz tube furnaces play an indispensable role in scientific experiments. Their design and performance are critical in a wide range of research fields, making them essential tools for many applications. High-Temperature Resistance First, the high-temperature resistance of quartz tube furnaces is one of their key advantages. Quartz, as a mineral with a high melting point, can withstand extreme temperatures, making it ideal for experiments that require elevated thermal conditions. For example, in materials science, researchers often need to study the physical and chemical properties of materials under high temperatures. In such cases, the quartz tube furnace becomes an invaluable tool. Precision in a Vacuum Environment The vacuum environment

Quartz tubes are widely used in industrial and laboratory applications due to their excellent heat resistance, chemical stability, and transparency. However, in certain high-purity applications, such as semiconductor manufacturing, optical instruments, and fiber optics, impurities in quartz tubes can negatively impact product performance. Therefore, removing or reducing impurities in quartz tubes is crucial. Below are some common purification methods along with their advantages and disadvantages: 1. Chemical Cleaning Method Overview: Use high-purity solvents (e.g., deionized water, ammonia, hydrofluoric acid), combined with ultrasonic cleaning, rinsing, or soaking, to remove impurities on the surface of quartz tubes. 2. High-Temperature Treatment Method Overview: Place the quartz tube in a high-temperature furnace to volatilize

Quartz tubes, made from high-purity silicon dioxide, are a specialized form of industrial glass with exceptional physical and chemical properties. Due to their efficient heat-generating capabilities, they are commonly used in devices such as electric heaters, ovens, and other heating equipment. Key Testing Methods for Quartz Tubes 1. Resistance Testing Resistance testing helps determine whether a quartz tube is functioning properly. 2. Power Supply Voltage Testing This test ensures that the quartz tube receives the correct voltage for optimal performance.
