Frequently Asked Questions
1、Why Use Advanced Ceramics?
A: Advanced ceramics possess advantages that metals and plastics cannot match: high hardness and wear resistance, high strength and resistance to deformation, corrosion and oxidation resistance, good stability and non-reactive properties, high temperature resistance, good insulation, and non-magnetic properties. In the process of technological development and in the aerospace industry, we desire a material that meets several performance requirements: it must be more wear-resistant than metals, withstand temperatures of around 2000 degrees Celsius, have low density, and be as lightweight as possible. However, we cannot find such a material among numerous metals (steel, copper, aluminum, silver, gold) and plastics. The scientific community has developed advanced ceramics, a material "new continent" possessing these superior properties.
2、How to reduce the price of ceramic products
A: There are several ways to reduce product prices:
1. Increase order quantity;
2. Reduce product precision;
3. Modify product structure to facilitate molding, sintering, and processing, thereby reducing scrap rate;
4. Use lower-priced materials such as alumina.
3、Is higher purity always better for advanced ceramic materials?
A: Among commonly used ceramics such as alumina, zirconia, and silicon nitride, alumina ceramics are the most widely used. For alumina ceramics, under the same forming process, higher purity is better. Of course, higher purity means higher price. Currently, the purity of precision alumina ceramic mechanical structural parts in the domestic market is generally 99%. 95% purity ceramic structural parts are generally used for electrical ceramic insulation parts with lower requirements. The alumina ceramic substrate used in electronics has a purity of 96%.
Besides the principle that higher purity is always better for alumina ceramic products, currently, zirconia and silicon nitride ceramics require the addition of trace elements before powder production to ensure smooth sintering and better performance. These trace elements are not impurities in the material, but rather part of a material formula developed through numerous trials. Before adding trace elements, the purity requirement for the main powder is extremely high, reaching over 99%. Therefore, silicon nitride and zirconia ceramic products with a purity of over 99% are currently not available on the market.
Our performance requirements for a product are not singular; we generally require several properties to be met. For example, ceramic substrates in electronics primarily need insulation, but we also desire better heat dissipation, lower density for thinner and lighter designs, and higher strength. When we have multiple requirements for the comprehensive performance of ceramics, we can start by adjusting the formula, adding other components to create composite ceramics that meet the product's usage requirements. With the addition of other ingredients, the issue of higher purity being always better no longer applies to composite ceramics.
