agglomerateLarge, coarse, angular rock fragments associated with lava flow that are ejected during explosive volcanic eruptions. Although they may appear to resemble sedimentary conglomerates, agglomerates are igneous rocks that consist almost wholly of angular or rounded lava fragments of varying size and shape. Some geologists sort agglomerates into bombs, blocks, and breccia. Bombs are ejected in a molten state, becoming rounded upon solidification, and blocks are erupted as solid fragments. Upon accumulation and solidification of the angular fragments (also known as pyroclastics), they form agglomerates. agglomerate a rock consisting of angular fragments of volcanic lava agglomerate [ə′gläm·ə·rət] (geology) A pyroclastic rock composed of angular rock fragments in a matrix of volcanic ash; typically occurs in volcanic vents. (metallurgy) A rigid mass of metallic particles that have been joined together by a powder metallurgical technique, such as sintering. How to thank TFD for its existence?

a given system, one of the most important parameters impacting the
mechanical, electrical or optical performance is the filler dispersion,
It is well known that large agglomerates tend to form a flaw, which
leads to mechanical failure. SootH and SootL aerosols were produced by means of a
diffusion flame from a mixture of propane and air (CAST, Matter
Engineering AG, Wohlen, Switzerland) at equal settings to ensure
particle agglomerates with high (SootH) or low OC (SootL) at the same
size distribution (Schroeppel et al. That reduces mixing of
colorant and dispersion of agglomerates by lowering the work done on the
melt. |
