Visualizing the Microdistribution of Zinc Borate in Oriented Strand Board Using X-Ray Microcomputed Tomography and SEM-EDX

<div>EDX spectrum and backscattered scanning electron microscope images of sections of OSB specimens containing a zinc borate additive: (a) EDX spectrum from point analysis of a white deposit in an OSB specimen. Note the prominent zinc peaks (arrowed) and the absence of boron peaks; (b) individual zinc borate particles in a void in an unleached OSB specimen; (c) individual zinc borate particles in lumens of cells (arrowed) in wood flakes in an unleached OSB specimen; (d) tightly packed zinc borate deposits in lumens of cells (arrowed) in wood flakes in an unleached OSB specimen. Scale bars are (b) 4 <i>μ</i>m; (c) 20 <i>μ</i>m; (d) 10 <i>μ</i>m.</div>
