炭化ケイ素の改質にはどのような技術が用いられますか？
After mechanical crushing, ultrafine Silicon powder has irregular particle shapes. Due to its small size and high surface energy, the particles easily agglomerate. This results in poor dispersion, which is unfavorable for ceramic forming and sintering. Therefore, silicon carbide surface modification is required. It improves the dispersion and stability of the powder. This also enhances the forming performance of the powder. There are many surface modification methods. Among them, surface coating modification and surface chemical modification are widely applied. Surface Coating Modification Surface coating modification involves mixing ultrafine powders with a modifier in a specific ratio in water or an organic medium. After magnetic stirring or ball mill for a […]
電子ペーストは単なる「スラリー」ではない。それは機能性粉末、ガラス粉末、およびキャリアの相乗効果である。
Electronic paste is a general term for paste-like or fluid electronic materials. It is typically applied through screen printing, inkjet printing, coating, pad printing, or 3D printing. The paste is deposited on substrates such as ceramics, glass, polymer films, silicon wafers, or metal bases. After sintering or curing, it forms functional films or patterns. It is widely used in thick-film circuits, MLCCs, multilayer chip inductors, photovoltaic cells, semiconductor packaging, display devices, and sensors. The paste carries multiple roles such as conductivity, resistance adjustment, dielectric, protection, and transparent conduction. At first glance, electronic paste looks like a sticky mass. In essence, it is a multiphase composite system. It usually consists of […]
ジェットミル：ガラス粉末粉砕に最適な装置
Many people, when they first hear the term “glass powder,” instinctively associate it with crushed glass particles or raw material for glass production. In fact, glass powder is a high-transparency, scratch-resistant filler with fine particle size, excellent dispersibility, high transparency, and good anti-settling performance. After surface modification, it gains strong affinity and steric hindrance, allowing it to disperse easily in coatings. Once film-forming, it enhances coating fullness and produces crystal-clear primers that maintain transparency while offering superior scratch resistance. Modern glass powder grinding technology further ensures uniform particle size distribution and improved performance in advanced coating systems. The primary raw material of glass powder is selected silica sand, with high-purity […]
