MgO mole ratios in the formulations were varied from 2.0 to 4.0, with fixed mole ratios of alumina and silica, to study the effect of MgO concentration on the coefficient of thermal expansion coefficient (CTE) and dielectric properties. The CTE values decreased from 2.5 × 10-6 to -2 × 10-6/K for samples with MgO mole ratios varied from 2.0 to 4.0, respectively. Dielectric permittivity and dielectric loss were measured from 1 MHz to 1.8 GHz for all formulations and showed the average value of ε′ = 5-6.5 and tan δ = 10-2. 2010-07-19T08:52:43Z 2010-07-19T08:52:43Z 2010-04-02 Article Journal of Alloys and Compounds, vol.494 (1-2), 2010, pages 256-260 0925-8388 http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6TWY-4Y4PVK3-2&_user=1659113&_coverDate=04%2F02%2F2010&_rdoc=1&_fmt=high&_orig=search&_sort=d&_docanchor=&view=c&_acct=C000054070&_version=1&_urlVersion=0&_userid=1659113&md5=f2051cab27c48f88097a4e295b77e178 http://hdl.handle.net/123456789/8320 en Elsevier B.
