Mica packages from Diedorf by Inver
In the electrical industry, mica is used as thermal protection and an insulator, offering significant technical benefits. Whether it's mica discs or mica packages from Diedorf – as an expert in mica plates and process engineering, we offer a wide range of mica products, including solutions for insulated semiconductor mounting. Explore our mica disc packages and choose one of the best and most sustainable options available on the market!
Mica – A Sustainable Natural Product with Diverse Applications
Our mica packages from Diedorf consist of natural mica, a material with a variety of special properties. Mica is a mineral extracted through mining and belongs to the monoclinic crystal system. It is composed of alkali-containing aluminum silicates, which can vary greatly in composition. As a result, there are many types of mica found in nature.
For technical purposes, the most commonly used types are colorless to light-colored, often ruby-red muscovite mica and the typically amber-colored phlogopite mica. The quality of the material is measured according to international standards, focusing on color, purity, individual crystal formation, hardness, and surface texture. High-quality mica with technical applications is characterized by the following key features:
- High oil and acid resistance
- High dielectric resistance
- Low dielectric losses
- High dielectric strength
- High temperature resistance
- Optical purity
- Excellent mechanical cleavage
Our mica packages from Diedorf can be used in both the electrical industry and as glass protection for sight glasses in water level and gauge indicators. By installing these packages, the glass is protected from high temperatures, high pressure, and surface erosion. Additionally, the material offers protection against acids, bases, and alkalis, while also providing excellent light transmission when of high quality.
Muscovite mica packages – Functionality meets optical purity
Our goal is not only to assist you in planning and executing your projects, but also to offer products of the highest quality. Our mica packages from Diedorf are made from top-quality muscovite, which stands out for its sustainable quality and numerous product advantages. Muscovite is characterized by its light to transparent color and its functional properties.
Muscovite mica packages provide an excellent, durable, and long-lasting solution when dealing with corrosive and material-damaging substances, as well as being one of the most resilient options for high-temperature protection. Thanks to their clarity and light transmission, they can be used for both optical and thermal applications due to their incredible stability and heat resistance.
The material is particularly suited for producing heat-resistant discs that protect against corrosive substances and acids. Muscovite is also ideal for manufacturing sight glasses, level indicators, and water gauges.

Mica packages from Diedorf – High-quality mica disc packages from the experts
Our mica packages from Diedorf are made of high-quality mica and are highly sought after in the glass and electrical industries. The mica packages consist of elastic, thin, and tough layers, and depending on the type of mica, they can vary in color. This variation is due to the organic nature of mica, a natural product whose composition and appearance depend on its specific makeup.
The diverse applications remain the same, ranging from thermal protection to purely optical uses. Take advantage of our many years of experience, explore our wide range of mica products, and request personalized advice if needed.
Mica Discs for Optical Applications by INVER
In industry and research today, processes are used that place high demands on different materials. Acid and extreme pressure are just a few of the challenges that, for example, mica discs for optical applications must withstand.
But why is mica so well suited for a variety of demanding uses? This is primarily due to the nature of mica. Depending on its purity, mica can be as transparent as ordinary glass. However, mica is much more durable than glass. After processing, mica can be used as glass protection in sight glasses, for instance. This ensures that the glass does not break, fog up, or become dull. To this day, not all possible uses of mica are known. Especially in semiconductor technology, the mineral is known for simplifying the production of insulated semiconductors. We see ourselves as partners for research, industry, and education. We prepare mica discs for optical applications. This is a lengthy and not necessarily easy process, as many individual steps must be carried out to perfection.
The advantages of mica discs for optical applications and more - compact and summarized
To better understand mica and especially the use of mica discs for optical applications, one should first focus on the mineral itself. Mica is mined and consists of individual aluminum silicates. These ensure that the appearance and nature of mica can vary greatly. This factor can make it quite challenging to find mica of the highest quality. After all, the color can reveal much about its composition. But the appearance, specifically its purity and surface structure, are also decisive factors. Mica with a pink tint, known as muscovite, is primarily used for all kinds of technical applications. Muscovite is considered a prime example of strong and durable mica.
In summary, regarding the highest quality mica, which is suitable for mica discs for all applications, it can be said that it has an astonishingly high resistance to oil and acid. Additionally, this quality of mica can be perfectly split in a purely mechanical way. This feature is what allows the production of thin yet extremely powerful mica discs for optical applications. Depending on the color and processability, we decide which product will be made from the pure mica. Only when absolute purity is achieved can mica discs for optical applications be produced from the material.
The mica package - many properties combined
A mica package that we put together for the customer contains a variety of individual mica flakes. This means that many individual properties come together. If the mica package is processed correctly, the positive properties combine, resulting in a particularly powerful end product.
As specialists in the further processing and categorization of the product, we support our customers in their own projects with all our expertise. With our many years of experience, we can quickly find the right mica, the form, and the type of processing. For example, if mica discs for optical applications are sought, the description of the project is usually enough to quickly find the right product. We are happy to go into more detail in a conversation and explain the benefits of each mica type for your project.
