Ceramic materials
[ Abstract ]: ceramic materials in our daily lives is a very important material, especially in our China, making ceramic since ancient times is our specialty. To the modern ceramics and the concept of functional happened a series of change, this paper focuses on the properties of ceramic materials, application and development prospect of doing a simple overview
[ Key words ]: ceramics, materials
Text: 1, overview: traditional ceramic material is clay, quartz, feldspar and other silicate materials, and modern ceramic materials are inorganic non-metallic materials collectively. Ceramic material is a kind of natural or synthetic powdered compounds, after molding or sintered at high temperature, the metal elements and non-metallic inorganic compounds constitute heterogeneous solid materials. Ceramic material with high temperature
resistance, corrosion resistance, wear resistance, abundant raw materials, low cost and many other advantages which are people who have been concerned. Now, ceramic
materials, metal materials, polymer materials are called the three major solid materials. 2, performance: ( 1): mechanical properties of ceramic materials with high hardness and excellent wear resistance, high elastic modulus, the tensile strength of steel of low compressive strength is high, the ceramic plastic, low toughness, pittle, almost no plasticity at room temperature.
( 2) mechanical properties : most of the ceramic hardness than the metal is much higher, especially good, often used as wear-resistant parts ( such as bearings, tool ). It has high elastic modulus and high pittleness, low tensile strength and high compressive strength, has strong heat function, with high temperature characteristics, its melting point is generally greater than 2000 DEG C. In addition, ceramic material also has a smaller thermal expansion coeff
