▎ 摘　　要

NOVELTY - The ceramic manufacturing method involves using lanthanum chromate, graphene and additives, preparing ceramic raw sheet using lanthanum chromate and the additive powder, arranging the graphene layer on the prepared ceramic raw sheet, heat pressing the ceramic raw sheet and the graphene layer, and sintering. USE - Manufacturing method of ceramic used in basalt drawing drain board (all claimed). ADVANTAGE - The method enables manufacture of ceramic with controlled porosity within 20%, and is not easy to crack, and has excellent high temperature resistance, conductivity, high strength, excellent bending resistance, fracture resistance, improved performance, and reduced production cost, and bears certain load. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for basalt drawing drain board that is formed of ceramic.
