Product Description

Silicon Carbide 320# Is Smelted By Resistance Furnace At High Temperature



1. Product Introduction

Silicon carbide, chemical formula for SiC, is made of quartz sand, petroleum coke (or coal coke), wood chips (adding salt for green silicon carbide production) and other raw materials, then smelting in a resistance furnace at high temperature, and it can also be called electrolon sand or refractory sand. Silicon carbide is divided into two kinds: black silicon carbide and green silicon carbide, are hexagonal crystal, specific gravity is 3.20~3.25g/cm3, Mohs hardness of silicon carbide is 9.5.


Our company strictly controls the quality of raw materials, smelting production with high standard raw materials, to ensure the quality of products. Among them, coal has the following characteristics: low ash, low sulfur, low phosphorus and high calorific value, high mechanical strength, high chemical activity, high specific resistance and so on; The content of SiO2 in the silica is greater than 99℅, and the selection and washing processing to produce uniform particle size. The silicon carbide powder was obtained by various chemical processes. Black silicon carbide containing SiC about 98.5%, its toughness is higher than green silicon carbide, mostly used for processing low tensile strength materials, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals. Green silicon carbide containing SiC more than 99%, good self-sharpening, mostly used for processing hard alloy, titanium alloy

nd optical glass, also used for honing cylinder liner and fine grinding high speed steel tools.
