Customer Reviews
This is the first time for our cooperation. They are indeed what we want. We look forward to working with you again in future.

—— Fred (USA)

Your ceramic tube is really good for our application, we will buy more in future.

—— Jessica Ferrara (Italy)

You are the best, your ceramic parts are perfect

—— Dalibor(Czech)

Our client satisfied with the Cordierite kiln shelf and sagger . But It would be better if the delivery time be shorter in our next order.

—— Van Nguyen (Viet Nam)

I hope you are fine and business is well. We recieved the perfect goods from you, your are the best.

1. Introduction 
Our Silicon carbide kiln shelves in multi-sided shapes designed for top-loading electric kilns were first introduced. These thin and lightweight kiln shelves are made from an advanced oxide-bonded silicon carbide composition that is distinguished from conventional oxide-bonded silicon carbide in that it is significantly stronger, thinner and much more resistant to oxidation. Kamtai kiln shelves are 19 times stronger and weigh 50% less than conventional 1-in.-thick cordierite kiln shelves. In addition, they are made flat to stay flat so there’s no warping, even after many firings under heavy loads.
While it is true that some forms of silicon carbide are specifically designed to conduct electricity (such as heating elements), the internal bond matrix—and especially the glassy, oxide layer that is intentionally fired onto the surface of Kiln shelves—dramatically lowers their electrical conductivity compared to other types of silicon carbide kiln shelves. As a result, the electrical conductivity value of  kiln shelf is low enough to be considered safe for use in top-loading electric kilns.
