What Are The Excellent Properties Of Alumina Ceramics

Alumina ceramics, primarily composed of alumina (AL2O3), serve as a crucial component in various technological applications, including thick film integrated circuits. These ceramics are recognized for their excellent conductivity, mechanical strength, and remarkable resistance to high temperatures.

It’s important to note that ultrasonic cleaning is required for alumina ceramics. Their versatility is a key factor, making them well-suited for applications in modern society where high-performance materials are in demand. However, during the machining process, edge chipping can occur, which presents a challenge for facilities engaged in ceramic processing.

How To Solve This Problem?

Several methods can be adopted to mitigate the issue of edge chipping when working with alumina ceramics. One effective approach involves allowing some extra material when drilling holes, subsequently grinding down the excess to achieve the desired dimensions. This not only maintains structural integrity but also enhances the overall finish of the ceramic piece.

Another technique is to utilize cutting tools with a smaller diameter during machining operations. This method entails using a spiral down technique, where the material is removed layer by layer. While this approach can be less efficient due to slower progression, it results in a smoother inner surface of the hole. Initially, a smaller diameter tool is used to create a pilot hole, which can then be expanded to the preferred size, although this could leave visible lines on the inner wall.

Alumina Ceramics Are Divided Into Two Types: High-Purity Type And Ordinary Type.

• High-purity alumina ceramics are defined by an Al2O3 content exceeding 99.9%. Their elevated sintering temperature and specific light transmission characteristics make them invaluable in the electronics industry for integrated circuit substrates and high-frequency insulating materials, as well as applications involving molten glass.
• Ordinary alumina ceramics, on the other hand, categorize themselves by Al2O3 content, including variants such as 99, 95, 90, and 85 ceramics. Notably, 99% alumina is commonly used for high-temperature crucibles and wear-resistant materials. The 95% variant is mainly for components requiring corrosion and wear resistance, while the 85% variety often has additives like talc to improve its properties and allow metal sealing.

Understanding both the characteristics and classifications of alumina ceramics is vital for their application in various fields. AnYiCheng specializes in precision ceramics products, capable of tailoring designs based on customer requirements.
