Oxide Bonded High Temperature Sic Kiln Shelves For High - Grade Ceramic Products
Oxide Bonded High Temperature Sic Kiln Shelves For High - Grade Ceramic Products
1. Introduction of Silicon carbide kiln shelf
In order to meet the requirements of high-grade ceramic kiln.We producted and researched new generation of high grade silicon carbide board and kiln shelf.According to the customer feedback information,it has long-term use no deformation,cracks,slag.Special for high-grade sanitary,high-grade ceramic products,it has no color pollution phenomenon.
Our Sic kiln shelf have ceramic pillar,ceramic plates,ceramic beams,ceramic fish plates.And our Sic kiln shelf has many sic materials,such as oxide bonded silicon carbide,recrystallizde sic.Oxide bonded sic refractory material has the following features:
