1 www.stellarcanada.com STELLAR CANADA INC. Ceramite The Wear Resistant Material Coal Fired Power Generation Applications

2 www.stellarcanada.com STELLAR CANADA INC. Elkem Fiskaa, today Elkem Fiskaa, 1969 Ceramite ® is a technology developed by Elkem Materials during research and devlopment of Elkem Microsilica ® 20 years of lab testing and coordinated industrial trials Today: Significant applications in several industries; primarily aluminium, cement and ferrous metals INTRODUCTION TO CERAMITE

3 www.stellarcanada.com STELLAR CANADA INC. Ceramite ® Microsilicia ® & Cement The Key to High Strength Bond Phase Microsilica - amorphous SiO 2 fume, (D= 0.1 - 1 micron) Improves particle packing efficiency in castable - fills in voids between larger aggregates. Less water needed for casting. Dense castables with low porosity Extreme Wear Resistance Impervious to Gas and Chemicals

4 www.stellarcanada.com STELLAR CANADA INC. *A 7.1 cm cube sample is pressed with a 300 N force against a grinding wheel that is coated with a fine grade corundum sand. The sample is rotated 22 times (1 campaign) after which it is cleaned and weighed. The grinding machine is cleaned after each campaign and new media is distributed on the grinding wheel. The test requires 18 campaigns. The Bohme Test results are expressed as the volume of material lost from the specimen in cm3 from the surface area exposed to wear.

10 www.stellarcanada.com STELLAR CANADA INC. Coal Chute Repair

11 www.stellarcanada.com STELLAR CANADA INC. Coal Chute Repair Customer previously repaired ceramic tile with beaded epoxy Would need repairs every 6 months Ongoing project since 2006

12 www.stellarcanada.com STELLAR CANADA INC. Burner/ Vortexer CERAMITE T

13 www.stellarcanada.com STELLAR CANADA INC. The Problem Customer uses Nitrite Bonded SiC tiles Tiles routinely crack and must be repaired every six months Ceramite Trowelable has been used as repair material for past 18 months Based on Ceramite performance, customer decided to trial complete vortex burner

14 www.stellarcanada.com STELLAR CANADA INC. Worn SiC Tile with Ceramite Patch

15 www.stellarcanada.com STELLAR CANADA INC. Welded Wire Mesh

16 www.stellarcanada.com STELLAR CANADA INC. Installing Overhead

17 www.stellarcanada.com STELLAR CANADA INC. Finished Installation

18 www.stellarcanada.com STELLAR CANADA INC.Summary Four hours required to weld in mesh Four hours to install Ceramite Installing SiC tiles requires 36 hours Customer intends to perform more complete installations during future outages
