COMPOSITION FOR ADHESION COMPRISING SIO2-B2O3-ZNO-BASED GLASS POWDER AND MGO OR MAGNESIUM COMPOUND WHICH BECOMES MGO WHEN HEATED AT 600 DEG.C, ADHESIVE MATERIAL CONTAINING THE COMPOSITION, AND ADHERED PRODUCT OBTAINED BY USING THE COMPOSITION OR THE MATERIAL

摘要

PURPOSE: Provided are a composition for adhesion which shows a low volume expansion of calcined body during calcination and improves the manufacturing efficiency of a cathode support part, an adhesive material containing the composition, and an adhered product obtained by using the composition or the adhesive material. CONSTITUTION: The composition comprises 85 wt% or more of a SiO2-B2O3-ZnO-based glass powder and MgO or a Mg compound powder which becomes MgO when heated at 600 deg.C, wherein the powder surface area of the MgO or the Mg compound is 0.4-8 m2 per 100 g of the composition. Preferably the Mg compound is MgCO3 and/or Mg(OH)2; MgO or the Mg compound has a specific surface area of 10-40 m2/g; and the glass powder has a mass average diameter of 5-35 micrometers. The adhesive material comprises 100 parts by weight of the composition; 1-6 parts by weight of a binder; and 0.05-2 parts by weight of a releasing agent.
