Abstract: PURPOSE: A glass-ceramic composition with high quality factor and low dielectric constant is provided to adjust the dielectric constant and quality factor depending on their purpose by varying mixing ratio and sorts of fillers. CONSTITUTION: A glass-ceramic composition is composed of zinc borosilicate glass and ceramic fillers. The ceramic fillers are selected from Al2O3, SiO2, mullite, and their mixture. The Q-factor is 4,200~40,000GHz and dielectric constant is 4.4~6.22(12GHz). The temperature factor of resonance frequency is -29~-14ppm/°C. The sintering temperature of the glass-ceramic composition is 900°C or lower. The Q-factor and dielectric constant can be adjusted by the ceramic fillers.

Abstract: An environment-friendly ceramic water-based cutting fluid composition is provided to prevent wear of a tool and to extend a life of the tool due to good flow of the fluid by a low viscosity, and excellent lubrication and refrigeration, and to prevent generation of bacteria and bad smell. An environment-friendly ceramic water-based cutting fluid composition includes a water-soluble polymer and ceramic powder. The composition is formed by melting the water-soluble polymer in water and dispersing the ceramic powder in the water solution. The water-soluble polymer includes water glass. The water-soluble polymer is any one or a compound of polyvinyl alcohol(PVA), cellulose, methyl cellulose, carboxymethyl cellulose(CMC), and starch.
