There's a Crack in My Refractory | Sperry | ...
Monolithic refractory goes through several chemical phases from installation to inservice. If a furnace has cracks due to thermal expansion stresses and we could map out all the stress, then all thermal stress cracking could be planned for, engineered and controlled by adding joints/seams or planned sections. Not all refractory cracking is due to expansion or mechanical stress. There are ...

Boundary Layers Refractory/Glass Melt and Glass Defects ...
In this paper the formation of boundary layers and their behaviour regarding corrosion and glass defect potential of different refractory/glass melt combinations will be discussed. The reaction between refractories and glass melts is determined by the diffusion of the different ions from the glass melt into the refractory material and vice versa.

Stone Defects
Stone is a product of nature, therefore, any kind of stone will include some possible defects. For some natural defects, we must reject it and pick them out, otherwise, the shipment will be poor quality. Below are some usual defects and you may find the reference pictures of them as follows, so that you can understand more about the "Nature" of stone. Refine Industrial Co.,LIMITED adheres ...

The eyes of 17 patients (81%) with refractory PEDs had reepithelized and four patients (19%) had still presented an epithelial defect by the end of the study followup period, although it had decreased in size. In patients where PED closure was achieved, mean time until reepithelization was ± days (median 23; range 7–114). In the remaining patients, a mean area reduction of % ...
Fused Cast AZS Block and Glass Defects – Refractory ...
· The mostly applied type of refractory in the glass industry, in direct contact with the glass melt, is fused cast AZS. Due to the interaction of the glass melt with fused cast AZS, glass defects like stones, knots and bubbles can be generated. Fused cast AZS block exudation is thought as the leading cause of knot and cord defects.

Background: Effective and tolerable therapeutic strategies for patients with refractory persistent epithelial defects (PEDs) are limited and generally provide poor outcomes. This retrospective case review describes four refractory cases of PEDs associated with recurrent corneal erosions (RCEs) and dry eye disease (DED), which were successfully treated with cyclosporine eye drops.
