Silicon carbide (SiC) plates serve as flat, stable supports inside high-temperature furnaces. This plate is over 99% SiC and rated for operating temperatures up to 1650°C.
SiC keeps its strength when hot: bending strength is 100-110 MPa at 1200°C, against 90-100 MPa at 20°C, so the plate resists sagging under a load at temperature. Thermal conductivity of 35-36 W/m.K spreads heat evenly under the sample, and an expansion coefficient below 4.8 x 10⁻⁶/°C helps it handle repeated heating and cooling.
With a hardness of 1800-2000 kg/mm², the surface resists wear and scratching from crucibles and sample boats.

What customers say about our store
Quick and reliable service provided! - Scheduled an appointment with Wayne the other day for a Dry Ice order pick up, he will go over and above for his customers to make sure we are well taken care of. Even with a broken foot !
Thanks again Wayne!
You've got my business!
Wayne there has an excellent store, he has everything, really nice stuff at good prices, ultimately very fair compared to others. I will certainly be going back for everything I need. Got some things from a different place and spent 50% more, just go see Wayne first, he seems like he wants to help you out more than sell you out the door.
