Quartz tubes are made from quartz sand, which can be either natural or synthetic. This material is highly pure, often 99.99% pure. It is known for its excellent thermal and electrical properties.

Glass tubes, on the other hand, are made from a mixture of various minerals and chemicals. These can include soda-lime, borosilicate, or other formulations. The purity and composition of glass are generally lower than that of quartz, affecting its thermal and mechanical properties.

2. Thermal Properties

One of the most significant advantages of quartz tubes is their ability to withstand high temperatures and thermal shock. Quartz tubes can operate at temperatures up to 1200°C and can handle rapid temperature changes from 1000°C to room temperature without breaking.

This is due to their extremely low coefficient of thermal expansion. Glass tubes, especially those made from soda-lime, cannot withstand such high temperatures or rapid temperature changes and are more prone to thermal shock.

3. Applications

Quartz tubes are used in high-temperature applications such as semiconductor manufacturing, vacuum brazing, and aerospace testing. Their transparency also makes them useful for applications where visibility is important, such as in some laboratory settings.

Glass tubes, while also used in laboratories and industry, are more commonly found in lower-temperature applications due to their lower thermal resistance.

4. Durability and Maintenance

Quartz tubes, while highly durable under extreme conditions, have limitations in terms of the number of heat-cool cycles they can withstand compared to other materials. For instance, when used at 1200°C, quartz tubes should not exceed 3 hours of continuous use due to their softening point at 1270 degrees.

What Is The Brazing Process? 5 Key Points To Understand

The brazing process is a metal-joining technique.

It involves using a filler metal with a lower melting point than the base metals being joined.

This process is similar to soldering but is done at higher temperatures.

The goal is to create stronger joints using stronger filler materials.

The filler metal is heated until it becomes molten.

It then flows into the joint by capillary action.

Upon cooling, the filler metal solidifies, creating a solid and durable joint.

Brazing can be performed using handheld or fixed torches in the open air.

For optimal results, it is recommended to remove as much oxygen as possible.

This is where furnace brazing comes into play.

Furnace brazing involves heating the entire assembly to a temperature where the braze alloy melts and flows into the joint.

By creating an environment with reduced oxygen levels, furnace brazing allows for better control over the brazing conditions.

This results in high-quality joints.

Almost any metal or ceramic can be brazed.

The key is that the braze alloy "wets" both surfaces to be joined.

Wetting refers to the ability of the filler metal to spread and adhere to the surfaces.

In some cases, oxide removal is necessary to achieve proper wetting.

Flux is often used to remove oxides when brazing in air.

In furnace brazing, the atmosphere or vacuum itself aids in oxide removal.

Different types of brazing processes exist.

These include torch brazing, furnace brazing, induction brazing, dip brazing, resistance brazing, infrared brazing, blanket brazing, electron beam and laser brazing, and braze welding.

Each process has its own advantages and applications depending on the specific requirements of the joint.

Overall, brazing is a versatile and widely used joining technique.

It can create strong, corrosion-resistant joints in various industries.

Brazing allows for the joining of different metals and ceramics.

This provides flexibility in design and assembly.

Furnace brazing, in particular, is commonly used for mass production of parts.

How Much Heat Do You Need To Braze? (5 Key Factors To Consider)

Brazing effectively requires the right amount of heat, which depends on the specific materials and brazing alloy used.

Generally, the brazing temperature should be at least 25ºC (50ºF) above the liquidus temperature of the braze alloy.

This ensures proper flow and reaction with the base metal.

The temperature is critical for achieving a strong joint, especially in cases involving large gaps or thin materials.

The time spent at the brazing temperature typically ranges from 5 to 10 minutes.

This ensures all parts reach the desired temperature uniformly.

How much heat do you need to braze? (5 Key Factors to Consider)

1. Temperature Setting

The brazing temperature is set based on the liquidus temperature of the braze alloy.

This is the temperature at which the alloy transitions from a solid to a liquid state.

To facilitate proper flow and wetting of the base metal, the temperature is raised at least 25ºC (50ºF) above this point.

This ensures that the molten alloy is reactive and can fill gaps effectively.

2. Duration at Brazing Temperature

The duration at the brazing temperature is crucial for ensuring that all sections of the part reach the necessary temperature uniformly.

This period typically lasts between 5 and 10 minutes but can extend longer for larger or denser loads.
