美国通用电气公司生产的“Lucalox”是一种类似金属的新陶瓷。这种陶瓷是由多晶体的α-氧化铝烧制而成。生产方法是:将粉状的氧化铝于室温下压制成型,然后进行密闭焙烧,使之形成α-氧化铝。在焙烧过程中,—般陶瓷中容易出现的细微小孔全部消除,使这种陶瓷具有类似金属的结构,呈半透明性质,有90%左右的可见光可以通过。这种陶瓷的密度约为3.98克/毫升,熔点为2040℃,介电常数为9.9(20兆周,20℃),可代替金
General Electric Company of the United States produced “Lucalox” is a new metal similar to the ceramic. This ceramic is made of polycrystalline α-alumina fired. The production method is: the powdered aluminum oxide at room temperature compression molding, and then closed roasted to form α-alumina. In the roasting process, all the tiny pores that are easy to appear in general ceramics are eliminated, so that the ceramic has a similar metal structure and is translucent. About 90% of the visible light can pass through. This ceramic has a density of about 3.98 g / ml, a melting point of 2040 ° C and a dielectric constant of 9.9 (20 trillion cycles at 20 ° C)
