Alotec is an improved version of the company’s CeraDur ceramic brick product. According to the company, advanced processing technology allows for precision controlled grain growth, which results in smaller, tighter grains with virtually no internal porosity or contamination. Only the highest purity alpha phase aluminum oxide, binders and grain growth inhibitors are used, the company reports. In addition, the latest technology in milling and spraying is employed to blend and produce a free flowing powder with exact particle size distribution. Sintering allows for tightly formed, smaller grains that permit entrapped porosity to pass along the grain boundaries.
