A reference condition analogous to that in the block-casting process was established using top/side heaters to supply heat and a water-cooled base to extract heat from the bottom of a graphite-clay crucible. This condition was modified by (a) changing the crucible bottom material to graphite, (b) increasing the length of the resulting ingot from 100 to 130 mm, and (c) turning off the heaters. Temperatures were measured within the melt and in the furnace environment. The grain macro-microstructures and the macrosegregation of impurities of the ingots were revealed. The cooling rates and solid–liquid interface velocity calculated with a mathematical model increase relative to the reference experiment when the graphite crucible bottom is used or when the top/side heaters are absent. The vertical temperature gradients also increase with the graphite bottom, but significantly decrease without the heaters. Most of the ingots exhibit a purified lower region of columnar grains with straight boundaries, free from intermetallic particles, and an upper region with mixed long and short columnar grains with serrated boundaries, precipitated particles, and higher impurity concentrations. Changing the crucible bottom material from graphite-clay to graphite increases the length of the purified region from 70 (reference condition) to 97 mm, whereas turning off the heaters completely eliminates this region.

Increasing production and productivity of oilseed brassica to meet out the projected demand of edible oils, crop management strategies need to be fabricated and implemented. The two varieties of mustard, RH 725 and RH 0749 display superior performance for yield and are recommended for farmers’ fields in north India. The present study evaluated the efficacy of silicon applied in the form of orthosilicic acid (OSA) for improving the physiological and biochemical performances, growth, and yield of recommended mustard varieties under field conditions, as a function of variety, stage, dose, and application time. OSA was applied as a foliar spray at 20, 30, and 40 ppm during vegetative and flowering stages to analyse its influence on plant growth, physiology, enzymatic and non-enzymatic antioxidant enzymes, and yield attributes. Application of OSA at 30 ppm at vegetative stage and 20 ppm at flowering stage, increased activity of antioxidant enzymes, superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and peroxidase (POX) and metabolites, ascorbic acid and glutathione; and decreased the levels of hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>), malondialdehyde (MDA), and relative stress injury (RSI), as compared to the respective untreated controls. The increase in antioxidant enzyme activity and ascorbic acid and glutathione content and protein content was greater in RH 0749 than RH 725.

The main focus is on assessing the strength characteristics of the briquettes and analyzing their efficiency in the silicon smelting process. The strength of the briquettes was studied by the dropping method. As a result, in terms of strength and other characteristics, it is highly advisable to use briquettes consisting of 65% of microsilica and 35% special coke screenings. The obtained batches of high-strength briquettes were tested for the smelting of metallurgical grade silicon in a large-scale laboratory ore-thermal furnace to replace the traditional charge mixtures (high-quality quartzites, petroleum coke, wood chips, etc.) with briquettes. It was established that the briquetted monocharge ensures more intensive reduction processes and improves melting conditions compared to the traditional charge. This leads to higher silicon recovery rates, which was confirmed by tests, during which the maximum recovery rate reached 83.1% with a 30% replacement of the charge with briquettes.
