Quartz composite ceramic material is alkylated modified by using HMDS. Mechanical properties, humidity resistance, dielectric properties, oxyacetylene ablation properties and adhesion properties of the materials are investigated. The results show that the alkylation modification can greatly improve humidity resistance of quartz composite ceramic material, slightly improve dielectric properties, oxyacetylene ablation properties and adhesion properties of the materials, and has no effect on mechanical properties of the materials.
