I ʻAukake, ʻo ke kumu kūʻai nui o ka pauka hao nitride silicon (Si: 48-52%, N: 30-33%, Fe: 13-15%), ʻo ke kumu kūʻai nui o ka mākeke ʻo RMB8000-8300 / tonne, kahi e pili ana. ʻO RMB1000 / tonne kiʻekiʻe ma mua o ka hoʻomaka ʻana o ka makahiki, he piʻi ma kahi o 15%, ʻoiai ʻoi aku ka nui o ke kumukūʻai ma mua o 20% i hoʻohālikelike ʻia me ka manawa like i ka makahiki i hala.(ʻO nā kumukūʻai ma luna nei nā kumukūʻai ʻauhau ʻauhau hale hana).

Ma muli o ka piʻi nui ʻana o ke kumukūʻai o ke kumu kūʻai o ka hao silika i kēia makahiki, ka hopena i ka piʻi ʻana o nā kumukūʻai hana o ka hao silika nitride, i ka hao silika 75B, no ka laʻana, ke kumu kūʻai o kēia manawa ma kahi kokoke i 8500-8700 yuan / ton, a i ka hoʻomaka ʻana o kēia makahiki ke kumu kūʻai ma kahi o 7000 yuan / ton.Ua piʻi nui ke kumukūʻai hana o nā mea maka, a ua koi ʻia ke kumukūʻai o ka pauka hao silicon nitride.

Me ka piʻi ʻana o ke kumukūʻai o ka hapa nui o nā mea maka, ua hoʻokau nui nā mea hana daimana i loko o ka hale, a ua nui nā hale hana e hoʻonui i nā kumukūʻai.

Ua hoʻomaopopo ʻia ʻo nā ʻoihana hana i kēia manawa ma Kina he paʻa, lawa ka lako, akā pili ʻia e ka pale ʻana a me ka mālama ʻana i nā maʻi maʻi, ʻoi aku ka liʻiliʻi o nā kaʻa, ʻoi aku ka kiʻekiʻe o nā kumukūʻai ma mua o ka wā ma mua, pono e mākaukau mua nā mea kūʻai aku.

Inā pono ʻoenā pad poni daimana, huila kiaha daimana, kāmaʻa wili daimana, papa wili daimanaetc, e hoʻokipa iā mākou.
