2 CERASURF WEAR MATERIALS CERASURF WEAR RESISTANT CERAMICS CoorsTek h been producing ceramic materials for over 100 years. We have the knowledge, capabilities, and experience to solve the most troublesome material handling wear problems. CeraSurf Fine-Grained, Direct-Sintered Silicon Carbide (SC-DS) Direct-sintered, SC-DS is a fine-grained silicon carbide offering the highest chemical and abrion resistant properties for the most challenging applications. With the most extensive wear resistant ceramic material product portfolio available in today s marketplace, CoorsTek specializes in providing advanced wear resistant ceramic materials and solutions that incree material handling wear life and reduce unnecessary downtime. Advanced Ceramics for Industrial Wear Applications CoorsTek engineered technical ceramics offer higher strength, abrion and corrosion resistance than traditional wear materials, such wear resistant steel, by much 10:1. Our CeraSurf technical ceramics exhibit long-lting wear in the most abrive environments. CoorsTek offers a broad range of alumin and silicon carbides to ensure ideal fit, form, and function. Let our wear experts will help you choose the best material for your particular wear conditions and budget. Alumin Used in heavy industry for years a cost-effective, wearresistant solution, CeraSurf alumin are lightweight and offer high durability, strength, and excellent abrion and corrosion resistance. CeraSurf, AD-92, AD-94 or AD-96 Each of these grades provides outstanding wear resistance for all types of material handling applications. All alumina grades offer the flexibility of being produced in standard rectangular shapes and custom engineered tile linings, well a variety of monolithic components. CeraSurf AD-92 and AD-96 are premium grade aluminum oxide ceramic materials engineered by CoorsTek for increed wear resistance. Regardless of the application, CoorsTek engineers will specify the correct aluminum oxide material for increed wear life in even the most demanding material handling systems. CeraSurf Fine-Grained Reaction-Bonded Silicon Carbide (SC-RB-210) Specifically designed for thin-wall applications, this finegrained, reaction-bonded silicon carbide offers very high wear resistance, and facilitates complex designs with tighter tolerances for monolithic elbow segments, burners, and tubes. CeraSurf Course-Blend, Reaction-Bonded Silicon Carbide (SC-RBX) SC-RBX is a course-grained, reaction-bonded silicon carbide with the ability to endure the most abrive environments and stronger impacts. SC-RBX is used to produce thicker wall components such large hydrocyclone liners. Rubber Vulcanization CoorsTek advanced wear resistant aluminum oxide materials are extensively utilized to extend material handling equipment life in the world s largest mineral processing super mines. CeraSurf AD-92 is typically vulcanized into rubber to enhance impact resistance, providing increed wear life to keep operations at peak performance. CeraSurf Zirconia-Toughened Alumina (ZTA) ZTA offers high strength and durability with the benefit of increed impact resistance through the addition of zirconium oxide. Silicon Carbide Available in fine or course-grained forms for varying applications, CoorsTek silicon carbide offers superior wear at high temperatures, yielding a long life in the most abrive environments.

3 PRE-ENGINEERED TILES Process Piping CoorsTek engineers and manufactures new piping systems, well individual piping components to incree material handling equipment life. Ceramic linings are pre-engineered with proper side angles to achieve full face-to-face contact and maximum interlock. Chutes Alumina ceramic properties offer 0% porosity and uniform density for significant reduction of chute plugging and wear. Cyclones CoorsTek cyclones are lined with standard and pre-engineered tile linings. Our engineers will select the proper ceramic material for specific applications. Ceramic Brick & Linings CoorsTek stocks a large selection of standard alumina ceramic tile sizes.

The change in temperature where a sharp decree in flexural strength is observed is listed DTc. Wear Resistance Impingement tests are run using a dry fused alumina abrive. Rubbing tests are run using a dry 240 grit fused alumina abrive. The indices in the chart are calculated by dividing the material volume loss by the volume loss of an AD-85 alumina control. The lower in the index, the better the wear resistance. 100 gm load Four point bend modulus of rupture *Ceramic property values vary somewhat with method of manufacture, size, and shape of part.
