‘Sintering’?
Although the term is unfamiliar in everyday life, our lives are in fact supported by ‘sintering’.
This section shows how ‘sintering’, which is all too familiar to us, is used.
powder metallurgy
‘Sintering’ has historically been used in powder metallurgy, where metal powders are formed to make metal products.
Powder metallurgy is based on metals that can be ground to powder, but can be mixed with powders of any number of metals.
Metals produced by powder metallurgy are used in many aspects of everyday life, such as golf heads, buttons on clothes and accessories.
Ceramics
Ceramics, which are widely used in everyday life, are also produced by ‘sintering’.
Ceramics are also tableware, fired from a mixture of silica stone (quartz) as well as clay.
You may not familiar with quartz but you should know quartz crystals.
Pottery
As with ceramics, ‘sintering’ occurs during low-temperature firing in pottery, where clay is kneaded and hardened.
Those made by low-temperature firing are not suitable for long-term use in water due to their water absorbency, but are used in flowerpots.
Snow
Snow that is silky smooth when it has just fallen but hardens over time as it accumulates is another form of “sintering,” a phenomenon similar to liquid crystal sintering.
Snowballs and snow sculptures also become hard because they are densely packed under pressure, a phenomenon similar to “sintering.
Winter play can actually be said to utilize the principle of sintering.
Once you know what ‘sintering’ is, you may start to look at things you normally use without thinking about them differently!
We offer a reliable SPS system that can sinter materials that are considered difficult to be sintered by conventional sintering technique, and can synthesize materials that achieve advanced performance and superior properties.
