日本钢铁公司开发出由 6种不同无机物所构成的、实际线胀系数为 0的新一代陶瓷。该新型陶瓷的线胀系数受具有不同线胀率的混合晶体抑制 ,因此每种晶粒的膨胀率互相抵消。新陶瓷的线胀系数非常低 ,为普通陶瓷的 1 /30 0。如此低的线胀系数相当于零线胀系数。与线胀系数为零的玻 Nippon Steel has developed a new generation of ceramics consisting of six different inorganics with an actual linear expansion coefficient of zero. The linear expansion coefficient of this new ceramic is suppressed by mixed crystals with different linear expansion rates, so that the expansion rates of each type of crystal cancel each other out. The linear expansion coefficient of the new ceramic is very low, for ordinary ceramic 1/30 0. Such a low linear expansion coefficient is equivalent to zero linear expansion coefficient.
