Abstract

The invention discloses a high-voltage ceramic insulated dark blue glaze which comprises the following components in parts by weight: 10-50 parts of high-potassium low-iron feldspar, 5-25 parts of Yichun quartz powder, 3-20 parts of Yunnan kaolin, 2-15 parts of Guangdong Xinhui soil, 2-10 parts of limestone, 2-10 parts of calcined talcum, 3-15 parts of spodumene, 1-3 parts of barium carbonate, 2-10 parts of albite and 1-8 cobalt blue agent. The glaze formula can enhance the mechanical, electric and thermal properties of the electric ceramic, and the properties exceed the GB8411 standard.

Description

technical field [0001] The invention belongs to the field of electric porcelain, and in particular relates to high-voltage porcelain insulating dark blue glaze. Background technique [0002] Electric porcelain is a component used in power systems that mainly supports and insulates, and sometimes also serves as a container for other electrical components. Therefore, there are high requirements for its mechanical properties, electrical properties, and environmental resistance (hot and cold, anti-pollution, aging, etc.). Electric ceramics need to have good mechanical properties to carry electrical conductors, and work stably and reliably under long-term mechanical loads (tensile, bending, torsion, and internal pressure resistance). It must also have good electrical properties and excellent insulation capabilities to ensure safety during operation. How to manufacture inductive porcelain with good mechanical and dielectric properties has always been a problem that technicians ha...
