Advanced or technical ceramics are very broad terms that encompass many different types of ceramics with vastly differing properties. To make things easier for you to choose the right material for your particular application, we have put together this simple guide which gives a general idea of the properties of our principal technical ceramics relative to each other.

Machinable ceramics are fully dense ceramics. They require no post heat treatment and can be machined with ordinary metalworking tools. Once machined, they need no further grinding or firing and are generally ready to use in their particular application.
Machinable ceramics are the perfect choice if rapid turn-round is required. They also provide the ideal basis for prototyping before moving up to harder materials. Typically the mechanical properties of machinable ceramics tend to be lower than that of non-machinable ceramics. They also tend to be much cheaper for small quantity orders.
The principal machinable ceramics we currently offer include:
Shapal Hi-M Soft has significantly stronger mechanical properties than Macor. However, this may not be an issue if your application does not require the material to withstand high mechanical loads. Macor is one of our most frequently used ceramics and is typically the most cost effective material for general technical ceramic applications. If you need more help in making your choice, please contact us.

In its solid form, Boron Nitride in is also a machinable ceramic. However, it has relatively poor mechanical properties when compared to Macor and Shapal. Boron Nitride is typically used because it has a very specific set of thermal properties that make it highly desirable when high temperature capabilities are required.
No-machinable ceramics are those that once fired can only be machined using diamond grinding methods or other specialist machining practices. Non-machinable ceramics offer a more extensive range of properties but require specialist tooling and longer lead times. This said, they can often be more cost effective when large quantities or very high performance is required.

Precision ceramic components:
High chemical stability: Precision ceramic materials are known for their excellent chemical stability, which can maintain the stability of their physical and chemical properties in a variety of harsh chemical environments. Ceramic materials usually have good corrosion resistance to corrosive substances such as acids, alkalis, and salts, which makes them perform well in highly corrosive media.
Oxidation resistance: At high temperatures, precision ceramic components can maintain their structural stability and are not prone to oxidation reactions. This characteristic makes precision ceramics have a significant advantage in high temperature, highly oxidizing environments.
Wide application: Due to its excellent chemical stability, precision ceramic components have a wide range of applications in chemical, energy, medical and other fields. For example, in the chemical industry, precision ceramics can be used to make corrosion-resistant reactors, pipes and valves. In the medical field, precision ceramics can be used to make artificial joints, dental repair materials and so on.
Precision granite components:
Relatively good chemical stability: Precision granite, as a natural stone, also has a certain chemical stability. However, compared with precision ceramics, its corrosion resistance may be slightly insufficient. In some strong acid, alkali or high salinity environments, granite may be subjected to a certain degree of erosion.
Limited application: Due to the relative lack of chemical stability, precision granite components may not be the best choice in some cases where chemical stability is required. For example, in the transport or storage of highly corrosive media, more chemically stable materials may be required.
Advantages of precision ceramic components
1. Stronger corrosion resistance: precision ceramic components have higher resistance to acid, alkali, salt and other corrosive substances, and can maintain their stability in a wider range of chemical environments.
2. Higher oxidation resistance: in high temperature environment, precision ceramics can maintain its structure stability, not easy to occur oxidation reaction, thus extending the service life.
3. Wider application fields: Due to its excellent chemical stability, precision ceramic components have a wide range of application prospects in many fields such as chemical industry, energy, and medical treatment.
In summary, from the point of view of chemical stability, precision ceramic components have stronger corrosion resistance and higher oxidation resistance than precision granite components, so they have significant advantages in some occasions where chemical stability is very high. These advantages make precision ceramic components widely used in many fields, and promote the development and innovation of related technologies.
