high strengthened partially crystallized silicate bodies and ceramics used to the composition of anorthite, diopside system crystallized frit

摘要

PURPOSE: A partially crystallized high strength silicate resin, and ceramics thereby are provided to form a partially crystallized base during a cooling process after sintering, by mixing an anorthite and a diopside-based crystalline frit with clay, kaolin, pyrophillite, etc. CONSTITUTION: A partially crystallized high strength silicate resin and ceramics thereby use an anorthite (CaOAl2O32SiO2) and a diopside-based crystalline frit (CaOAl2O32SiO2). The diopside-based crystalline frit includes 10% or less of Al2O3 or B2O3 as a melting accelerator and includes 15% or less of calcium phosphate, zrO2, and siO2. The partially crystallized high strength silicate resin and the ceramics have an anorthite (CaOAl2O32SiO2), diopside-based crystalline frit (CaOAl2O32SiO2), and mullite (3Al2O32SiO2) crystalline phase and an cordierite (2CaO2MgO5SiO2) and cristobalite (SiO2) crystalline phase.
