1. Introduction
Our company produces products Used silicon carbide as main
material, upon request, with various powder additives, through
mixing, molding, drying, which is characterized by high temperature
flexural strength, thermal shock stability, high thermal
conductivity, wear resistance, anti-corrosion properties of various
advantages such as the atmosphere is the ideal energy industrial
furnace.
Refractory silicon carbide kiln shelves, also known as carborundum,
is a compound of silicon and carbon with a chemical formula SiC. is
made through high temperature sintering, adopting the higher
quality raw materials. It has characteristics of stable
performance, excellent thermal shock resistance, oxidation
resistance, long life, thin volume but high bulk density. Its good
thermal conductivity can assure to save energy at maximum level.
