The ceramic buttons are mainly divided into two categories: ordinary ceramic buttons and special ceramic buttons. The common ceramic buttons are formed by combining common porcelain materials such as sintering, glazing, surface decoration and metal bottom brackets.
The reason why ordinary ceramic buttons are welcomed is that after the glazing treatment, the button surface is decorated with patterns, colorful, brightness is very good, the decorative effect is very obvious, and the ceramic material has a high surface hardness, excellent wear resistance. However, due to the limitation of production methods and technology level, the production volume is not large and the cost is high.
Special ceramic buttons are made of high-strength ceramic materials such as zirconia, etc., after high-pressure forming and re-sintering. The button has a very high mechanical strength and is called a non-broken button. The price is relatively high. It is mainly used as a wearable shirt button.
